Factors that 42 space the perform of hopeful and an adverse whole numbers that deserve to be split evenly into 42. An unfavorable factors the 42 room just determinants with a negative sign. The number 42 is far-ranging and is an even composite number which method that it has actually several factors, in this case, 42 has 8 factors. In this lesson, we will certainly calculate the components of 42, its element factors, and its components in pairs. We will certainly also shot a few solved examples to understand this object better.

What are factors of 42?

Factors that a number space the numbers which division the provided number exactly without leaving any kind of remainder. Factors the 42 are 1, 2, 3, 6, 7, 14, 21 and 42.

How to calculation the factors of 42?

We deserve to use different methods like prime factorization and the department method to calculate the components of 42. In prime factorization, us express 42 together the product that its prime factors and also in the department method, we look because that numbers that division 42 specifically without a remainder.


Factors that 42 by element Factorization


Prime factorization way expressing a number in terms of the product that its element factors. We have the right to do this making use of the department method or by making use of a element tree.

Prime factorization by Division:

Step 1: The number 42 is divided by the smallest prime number which divides 42 exactly, i.e. It pipeline a remainder 0.Step 2: The quotient is then divided by the the smallest or 2nd smallest element number and the process continues it rotates the quotient cannot be more divided.Step 3: Let united state divide 42 through the element number 2 i.e 42 ÷ 2 = 21.Step 4: Now we have to divide the quotient 21 through the next the very least prime number.Step 5: Since 21 is one odd number, the is no divisible by 2. Let us shot dividing it by 3 which is 21 ÷ 3 = 7.Step 6: 7 is a prime number and we cannot divide it further.Step 7: Therefore, the prime components of 42 room 2, 3, and 7.

Prime administer of 42 = 2 × 3 × 7

Prime administer by factor Tree

Since we are finding the prime components of 42, they will certainly be inserted as the root of our factor tree. Next, we create a pair of components (two numbers, once multiplied, give 42) as branches.

*

3 and 7 are prime numbers and also at this point, the variable tree ends. Let united state express 42 in terms of the product that its element factors.

42 = 2 × 3 × 7

Viola! We have done the element factorization. Right here is a straightforward activity to try on your own. Instead of 2 × 21, if we had actually used 6 × 7, carry out you think we would get the exact same factors? have the right to you draw the factor tree through 6 and also 7 together the branches?

Prime factorization by Upside-Down Division

This an approach is referred to as the upside-down department because the division symbol is flipped upside down. In this method, we divide 42 through the the smallest prime number 2 (if the number is odd, we start with 3). 7 is a element number. The is divisible only by 7. We protect against the department when us reach 1.

*

Therefore, 42 can be expressed as a product the its prime factors as 2 × 3 × 7. Explore factors utilizing illustrations and interactive examples:

Think Tank:

8 × 21 ÷ 4 = 42, go this average 8 and 21 ÷ 4 are components of 42? Think!10.5 × 4 = 42, room 10.5 and also 4 factors of 42?Can a number greater than 42 be its factor?

Factors that 42 in Pairs

Factor pairs are the two numbers which, once multiplied, provide the number 42.

1 × 42 = 422 × 21 = 423 × 14 = 426 × 7 = 42

Therefore, the pair determinants of 42 space (1,42), (2,21), (3,14), and also (6,7). Because the product the two negative numbers is positive, i.e. (-) × (-) = (+), the element pairs of 42 likewise include (-1,-42), (-2,-21), (-3,-14), and also (-6,-7). Yet let us focus on the positive determinants in this lesson.

We division 42 by natural numbers and see i m sorry numbers leaving a remainder 0. The numbers which division 42 precisely without any type of remainder are the components of 42.

Division method to Find components of 42:

*

We check out that as soon as 42 is divided by 1, 2, 3, 6, 7, 14, 21, and 42, it leaves no remainder. Hence, they are determinants of 42.

Important Notes:

The numbers which we multiply to obtain 42 are the components of 42.Factors of 42 are 1, 2, 3, 6, 7, 14, 21, and also 42.1 is a global factor. The is a factor of all numbers. The number chin is a variable of the number together it divides itself exactly.Factor pairs are the bag of 2 numbers which, once multiplied, offer the number. Aspect pairs that 42 space (1, 42), (2, 21), (3,14), and also (6,7).
