How to Find the Factors of 671?

To find the factors of 671, we will have to find the list of numbers that would divide 671 without leaving any remainder.

• 671/61 = 11; therefore, 61 is a factor of 671 and 11 is also a factor of 671.
• 671/671 = 1; therefore, 671 is a factor of 671 and 1 is also a factor of 671.

Similarly we can find other factors. Hence, the factors of 671 are 1, 11, 61, 671.

• Factors of 20 - The factors of 20 are 1, 2, 4, 5, 10, 20
• Factors of 90 - The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
• Factors of 19 - The factors of 19 are 1, 19

The number 671 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 671. The first step is to divide the number 671 with the smallest prime factor, here it is 11. We keep dividing until it gives a non-zero remainder.

• 671 ÷ 11 = 61

Further dividing 61 by 11 gives a non-zero remainder. So we stop the process and continue dividing the number 61 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 671 can be written as 11¹ × 61¹ where 11, 61 are prime.

Pair factors of 671 are the pairs of numbers that when multiplied give the product 671. The factors of 671 in pairs are:

• 1 × 671 = (1, 671)
• 11 × 61 = (11, 61)

Negative pair factors of 671 are:

• -1 × -671 = (-1, -671)
• -11 × -61 = (-11, -61)

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