Given numbers are 220, 574, 621, 651

The list of prime factors of all numbers are

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 574 are 2 x 7 x 41

Prime factors of 621 are 3 x 3 x 3 x 23

Prime factors of 651 are 3 x 7 x 31

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 220, 574, 621, 651

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(220, 574) = 63140

GCD(220, 574) = ( 220 x 574 ) / 63140

= 220 / 574

= 220

Step2:

LCM(2, 621) = 1242

GCD(2, 621) = ( 2 x 621 ) / 1242

= 2 / 621

= 2

Step3:

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

= 1 / 651

= 1

So, Greatest Common Divisor of 220, 574, 621, 651 is 1
