Given numbers are 220, 553, 20, 951

The list of prime factors of all numbers are

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

Prime factors of 553 are 7 x 79

Prime factors of 20 are 2 x 2 x 5

Prime factors of 951 are 3 x 317

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

Given numbers are 220, 553, 20, 951

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

Apply this formula for all numbers.

Step1:

LCM(220, 553) = 121660

GCD(220, 553) = ( 220 x 553 ) / 121660

= 220 / 553

= 220

Step2:

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

= 1 / 20

= 1

Step3:

LCM(1, 951) = 951

GCD(1, 951) = ( 1 x 951 ) / 951

= 1 / 951

= 1

So, Greatest Common Divisor of 220, 553, 20, 951 is 1
