Factors of 851 are pairs of those numbers whose products result in 851. These factors are either prime numbers or composite numbers.

How to Find the Factors of 851?

To find the factors of 851, we will have to find the list of numbers that would divide 851 without leaving any remainder.

• 851/37 = 23; therefore, 37 is a factor of 851 and 23 is also a factor of 851.
• 851/851 = 1; therefore, 851 is a factor of 851 and 1 is also a factor of 851.

Similarly we can find other factors. Hence, the factors of 851 are 1, 23, 37, 851.

• Factors of 29 - The factors of 29 are 1, 29
• Factors of 78 - The factors of 78 are 1, 2, 3, 6, 13, 26, 39, 78
• Factors of 10 - The factors of 10 are 1, 2, 5, 10

The number 851 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 851. The first step is to divide the number 851 with the smallest prime factor, here it is 23. We keep dividing until it gives a non-zero remainder.

• 851 ÷ 23 = 37

Further dividing 37 by 23 gives a non-zero remainder. So we stop the process and continue dividing the number 37 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 851 can be written as 23¹ × 37¹ where 23, 37 are prime.

Pair factors of 851 are the pairs of numbers that when multiplied give the product 851. The factors of 851 in pairs are:

• 1 × 851 = (1, 851)
• 23 × 37 = (23, 37)

Negative pair factors of 851 are:

• -1 × -851 = (-1, -851)
• -23 × -37 = (-23, -37)

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