How to Find the Factors of 423?

To find the factors of 423, we will have to find the list of numbers that would divide 423 without leaving any remainder.

• 423/1 = 423; therefore, 1 is a factor of 423.
• 423/47 = 9; therefore, 47 is a factor of 423.

Similarly we can find other factors. Hence, the factors of 423 are 1, 3, 9, 47, 141, 423.

• Factors of 75 - The factors of 75 are 1, 3, 5, 15, 25, 75
• Factors of 38 - The factors of 38 are 1, 2, 19, 38
• Factors of 54 - The factors of 54 are 1, 2, 3, 6, 9, 18, 27, 54

The number 423 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 423. The first step is to divide the number 423 with the smallest prime factor, here it is 3. We keep dividing until it gives a non-zero remainder.

• 423 ÷ 3 = 141
• 141 ÷ 3 = 47

Further dividing 47 by 3 gives a non-zero remainder. So we stop the process and continue dividing the number 47 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 423 can be written as 3² × 47¹ where 3, 47 are prime.

Pair factors of 423 are the pairs of numbers that when multiplied give the product 423. The factors of 423 in pairs are:

• 1 × 423 = (1, 423)
• 3 × 141 = (3, 141)
• 9 × 47 = (9, 47)

Negative pair factors of 423 are:

• -1 × -423 = (-1, -423)
• -3 × -141 = (-3, -141)
• -9 × -47 = (-9, -47)

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