How to Find the Factors of 909?

To find the factors of 909, we will have to find the list of numbers that would divide 909 without leaving any remainder.

• 909/303 = 3; therefore, 303 is a factor of 909 and 3 is also a factor of 909.
• 909/101 = 9; therefore, 101 is a factor of 909 and 9 is also a factor of 909.

Similarly we can find other factors. Hence, the factors of 909 are 1, 3, 9, 101, 303, 909.

The number 909 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 909. The first step is to divide the number 909 with the smallest prime factor, here it is 3. We keep dividing until it gives a non-zero remainder.

• 909 ÷ 3 = 303
• 303 ÷ 3 = 101

Further dividing 101 by 3 gives a non-zero remainder. So we stop the process and continue dividing the number 101 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 909 can be written as 3² × 101¹ where 3, 101 are prime.

Pair factors of 909 are the pairs of numbers that when multiplied give the product 909. The factors of 909 in pairs are:

• 1 × 909 = (1, 909)
• 3 × 303 = (3, 303)
• 9 × 101 = (9, 101)

Negative pair factors of 909 are:

• -1 × -909 = (-1, -909)
• -3 × -303 = (-3, -303)
• -9 × -101 = (-9, -101)

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