So, the GCD (220, 531, 20, 728) = 1.

Given numbers are 220, 531, 20, 728

The list of prime factors of all numbers are

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

Prime factors of 531 are 3 x 3 x 59

Prime factors of 20 are 2 x 2 x 5

Prime factors of 728 are 2 x 2 x 2 x 7 x 13

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

Given numbers are 220, 531, 20, 728

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

Apply this formula for all numbers.

Step1:

LCM(220, 531) = 116820

GCD(220, 531) = ( 220 x 531 ) / 116820

= 220 / 531

= 220

Step2:

LCM(1, 20) = 20

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

= 1 / 20

= 1

Step3:

LCM(1, 728) = 728

GCD(1, 728) = ( 1 x 728 ) / 728

= 1 / 728

= 1

So, Greatest Common Divisor of 220, 531, 20, 728 is 1
