How to Find the Factors of 620?

To find the factors of 620, we will have to find the list of numbers that would divide 620 without leaving any remainder.

• 620/310 = 2; therefore, 310 is a factor of 620 and 2 is also a factor of 620.
• 620/155 = 4; therefore, 155 is a factor of 620 and 4 is also a factor of 620.

Similarly we can find other factors. Hence, the factors of 620 are 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620.

• Factors of 11 - The factors of 11 are 1, 11
• Factors of 23 - The factors of 23 are 1, 23
• Factors of 128 - The factors of 128 are 1, 2, 4, 8, 16, 32, 64, 128
• Factors of 45 - The factors of 45 are 1, 3, 5, 9, 15, 45

The number 620 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 620. The first step is to divide the number 620 with the smallest prime factor, here it is 2. We keep dividing until it gives a non-zero remainder.

• 620 ÷ 2 = 310
• 310 ÷ 2 = 155

Further dividing 155 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 155 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 620 can be written as 2² × 5¹ × 31¹ where 2, 5, 31 are prime.

Pair factors of 620 are the pairs of numbers that when multiplied give the product 620. The factors of 620 in pairs are:

• 1 × 620 = (1, 620)
• 2 × 310 = (2, 310)
• 4 × 155 = (4, 155)
• 5 × 124 = (5, 124)
• 10 × 62 = (10, 62)
• 20 × 31 = (20, 31)

Negative pair factors of 620 are:

• -1 × -620 = (-1, -620)
• -2 × -310 = (-2, -310)
• -4 × -155 = (-4, -155)
• -5 × -124 = (-5, -124)
• -10 × -62 = (-10, -62)
• -20 × -31 = (-20, -31)

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