How to Find the Factors of 445?

To find the factors of 445, we will have to find the list of numbers that would divide 445 without leaving any remainder.

• 445/89 = 5; therefore, 89 is a factor of 445 and 5 is also a factor of 445.
• 445/445 = 1; therefore, 445 is a factor of 445 and 1 is also a factor of 445.

Similarly we can find other factors. Hence, the factors of 445 are 1, 5, 89, 445.

• Factors of 11 - The factors of 11 are 1, 11
• Factors of 25 - The factors of 25 are 1, 5, 25
• Factors of 54 - The factors of 54 are 1, 2, 3, 6, 9, 18, 27, 54

The number 445 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 445. The first step is to divide the number 445 with the smallest prime factor, here it is 5. We keep dividing until it gives a non-zero remainder.

• 445 ÷ 5 = 89

Further dividing 89 by 5 gives a non-zero remainder. So we stop the process and continue dividing the number 89 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 445 can be written as 5¹ × 89¹ where 5, 89 are prime.

Pair factors of 445 are the pairs of numbers that when multiplied give the product 445. The factors of 445 in pairs are:

• 1 × 445 = (1, 445)
• 5 × 89 = (5, 89)

Negative pair factors of 445 are:

• -1 × -445 = (-1, -445)
• -5 × -89 = (-5, -89)

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