Given numbers are 635, 484, 252, 420

The list of prime factors of all numbers are

Prime factors of 635 are 5 x 127

Prime factors of 484 are 2 x 2 x 11 x 11

Prime factors of 252 are 2 x 2 x 3 x 3 x 7

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 635, 484, 252, 420

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

Apply this formula for all numbers.

Step1:

LCM(635, 484) = 307340

GCD(635, 484) = ( 635 x 484 ) / 307340

= 635 / 484

= 635

Step2:

LCM(1, 252) = 252

GCD(1, 252) = ( 1 x 252 ) / 252

= 1 / 252

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 635, 484, 252, 420 is 1
