Given numbers are 520, 568, 180, 421

The list of prime factors of all numbers are

Prime factors of 520 are 2 x 2 x 2 x 5 x 13

Prime factors of 568 are 2 x 2 x 2 x 71

Prime factors of 180 are 2 x 2 x 3 x 3 x 5

Prime factors of 421 are 421

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

Given numbers are 520, 568, 180, 421

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

Apply this formula for all numbers.

Step1:

LCM(520, 568) = 36920

GCD(520, 568) = ( 520 x 568 ) / 36920

= 520 / 568

= 520

Step2:

LCM(8, 180) = 360

GCD(8, 180) = ( 8 x 180 ) / 360

= 8 / 180

= 8

Step3:

LCM(4, 421) = 1684

GCD(4, 421) = ( 4 x 421 ) / 1684

= 4 / 421

= 4

So, Greatest Common Divisor of 520, 568, 180, 421 is 1
