Given numbers are 420, 638, 759, 202

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 638 are 2 x 11 x 29

Prime factors of 759 are 3 x 11 x 23

Prime factors of 202 are 2 x 101

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

Given numbers are 420, 638, 759, 202

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

Apply this formula for all numbers.

Step1:

LCM(420, 638) = 133980

GCD(420, 638) = ( 420 x 638 ) / 133980

= 420 / 638

= 420

Step2:

LCM(2, 759) = 1518

GCD(2, 759) = ( 2 x 759 ) / 1518

= 2 / 759

= 2

Step3:

LCM(1, 202) = 202

GCD(1, 202) = ( 1 x 202 ) / 202

= 1 / 202

= 1

So, Greatest Common Divisor of 420, 638, 759, 202 is 1
