How to Find the Factors of 551?

To find the factors of 551, we will have to find the list of numbers that would divide 551 without leaving any remainder.

• 551/29 = 19; therefore, 29 is a factor of 551 and 19 is also a factor of 551.
• 551/551 = 1; therefore, 551 is a factor of 551 and 1 is also a factor of 551.

Similarly we can find other factors. Hence, the factors of 551 are 1, 19, 29, 551.

• Factors of 57 - The factors of 57 are 1, 3, 19, 57
• Factors of 63 - The factors of 63 are 1, 3, 7, 9, 21, 63

The number 551 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 551. The first step is to divide the number 551 with the smallest prime factor, here it is 19. We keep dividing until it gives a non-zero remainder.

• 551 ÷ 19 = 29

Further dividing 29 by 19 gives a non-zero remainder. So we stop the process and continue dividing the number 29 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 551 can be written as 19¹ × 29¹ where 19, 29 are prime.

Pair factors of 551 are the pairs of numbers that when multiplied give the product 551. The factors of 551 in pairs are:

• 1 × 551 = (1, 551)
• 19 × 29 = (19, 29)

Negative pair factors of 551 are:

• -1 × -551 = (-1, -551)
• -19 × -29 = (-19, -29)

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