Given numbers are 477, 420, 356, 421

The list of prime factors of all numbers are

Prime factors of 477 are 3 x 3 x 53

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 356 are 2 x 2 x 89

Prime factors of 421 are 421

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

Given numbers are 477, 420, 356, 421

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

Apply this formula for all numbers.

Step1:

LCM(477, 420) = 66780

GCD(477, 420) = ( 477 x 420 ) / 66780

= 477 / 420

= 477

Step2:

LCM(3, 356) = 1068

GCD(3, 356) = ( 3 x 356 ) / 1068

= 3 / 356

= 3

Step3:

LCM(1, 421) = 421

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

= 1 / 421

= 1

So, Greatest Common Divisor of 477, 420, 356, 421 is 1
