How to Find the Factors of 291?

To find the factors of 291, we will have to find the list of numbers that would divide 291 without leaving any remainder.

• 291/3 = 97; therefore, 3 is a factor of 291 and 97 is also a factor of 291.
• 291/1 = 291; therefore, 1 is a factor of 291 and 291 is also a factor of 291.

Similarly we can find other factors. Hence, the factors of 291 are 1, 3, 97, 291.

• Factors of 66 - The factors of 66 are 1, 2, 3, 6, 11, 22, 33, 66
• Factors of 39 - The factors of 39 are 1, 3, 13, 39

The number 291 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 291. The first step is to divide the number 291 with the smallest prime factor, here it is 3. We keep dividing until it gives a non-zero remainder.

• 291 ÷ 3 = 97

Further dividing 97 by 3 gives a non-zero remainder. So we stop the process and continue dividing the number 97 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 291 can be written as 3¹ × 97¹ where 3, 97 are prime.

Pair factors of 291 are the pairs of numbers that when multiplied give the product 291. The factors of 291 in pairs are:

• 1 × 291 = (1, 291)
• 3 × 97 = (3, 97)

Negative pair factors of 291 are:

• -1 × -291 = (-1, -291)
• -3 × -97 = (-3, -97)

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