Given numbers are 420, 637, 793, 574

The list of prime factors of all numbers are

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

Prime factors of 637 are 7 x 7 x 13

Prime factors of 793 are 13 x 61

Prime factors of 574 are 2 x 7 x 41

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

Given numbers are 420, 637, 793, 574

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

Apply this formula for all numbers.

Step1:

LCM(420, 637) = 38220

GCD(420, 637) = ( 420 x 637 ) / 38220

= 420 / 637

= 420

Step2:

LCM(7, 793) = 5551

GCD(7, 793) = ( 7 x 793 ) / 5551

= 7 / 793

= 7

Step3:

LCM(1, 574) = 574

GCD(1, 574) = ( 1 x 574 ) / 574

= 1 / 574

= 1

So, Greatest Common Divisor of 420, 637, 793, 574 is 1
