Given numbers are 473, 788, 355, 420

The list of prime factors of all numbers are

Prime factors of 473 are 11 x 43

Prime factors of 788 are 2 x 2 x 197

Prime factors of 355 are 5 x 71

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

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

Given numbers are 473, 788, 355, 420

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

Apply this formula for all numbers.

Step1:

LCM(473, 788) = 372724

GCD(473, 788) = ( 473 x 788 ) / 372724

= 473 / 788

= 473

Step2:

LCM(1, 355) = 355

GCD(1, 355) = ( 1 x 355 ) / 355

= 1 / 355

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 473, 788, 355, 420 is 1
