How to Find the Factors of 545?

To find the factors of 545, we will have to find the list of numbers that would divide 545 without leaving any remainder.

• 545/5 = 109; therefore, 5 is a factor of 545 and 109 is also a factor of 545.
• 545/1 = 545; therefore, 1 is a factor of 545 and 545 is also a factor of 545.

Similarly we can find other factors. Hence, the factors of 545 are 1, 5, 109, 545.

• Factors of 100 - The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, 100
• Factors of 41 - The factors of 41 are 1, 41

The number 545 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 545. The first step is to divide the number 545 with the smallest prime factor, here it is 5. We keep dividing until it gives a non-zero remainder.

• 545 ÷ 5 = 109

Further dividing 109 by 5 gives a non-zero remainder. So we stop the process and continue dividing the number 109 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 545 can be written as 5¹ × 109¹ where 5, 109 are prime.

Pair factors of 545 are the pairs of numbers that when multiplied give the product 545. The factors of 545 in pairs are:

• 1 × 545 = (1, 545)
• 5 × 109 = (5, 109)

Negative pair factors of 545 are:

• -1 × -545 = (-1, -545)
• -5 × -109 = (-5, -109)

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