How to Find the Factors of 637?

To find the factors of 637, we will have to find the list of numbers that would divide 637 without leaving any remainder.

• 637/637 = 1; therefore, 637 is a factor of 637.
• 637/7 = 91; therefore, 7 is a factor of 637.

Similarly we can find other factors. Hence, the factors of 637 are 1, 7, 13, 49, 91, 637.

• Factors of 96 - The factors of 96 are 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 96
• Factors of 8 - The factors of 8 are 1, 2, 4, 8

The number 637 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 637. The first step is to divide the number 637 with the smallest prime factor, here it is 7. We keep dividing until it gives a non-zero remainder.

• 637 ÷ 7 = 91
• 91 ÷ 7 = 13

Further dividing 13 by 7 gives a non-zero remainder. So we stop the process and continue dividing the number 13 by the next smallest prime factor. We stop ultimately if the next prime factor doesn't exist or when we can't divide any further.

So, the prime factorization of 637 can be written as 7² × 13¹ where 7, 13 are prime.

Pair factors of 637 are the pairs of numbers that when multiplied give the product 637. The factors of 637 in pairs are:

• 1 × 637 = (1, 637)
• 7 × 91 = (7, 91)
• 13 × 49 = (13, 49)

Negative pair factors of 637 are:

• -1 × -637 = (-1, -637)
• -7 × -91 = (-7, -91)
• -13 × -49 = (-13, -49)

NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
