Given numbers are 531, 728, 421, 480

The list of prime factors of all numbers are

Prime factors of 531 are 3 x 3 x 59

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

Prime factors of 421 are 421

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

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

Given numbers are 531, 728, 421, 480

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

Apply this formula for all numbers.

Step1:

LCM(531, 728) = 386568

GCD(531, 728) = ( 531 x 728 ) / 386568

= 531 / 728

= 531

Step2:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 531, 728, 421, 480 is 1
