Given numbers are 632, 615, 420, 774

The list of prime factors of all numbers are

Prime factors of 632 are 2 x 2 x 2 x 79

Prime factors of 615 are 3 x 5 x 41

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

Prime factors of 774 are 2 x 3 x 3 x 43

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

Given numbers are 632, 615, 420, 774

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

Apply this formula for all numbers.

Step1:

LCM(632, 615) = 388680

GCD(632, 615) = ( 632 x 615 ) / 388680

= 632 / 615

= 632

Step2:

LCM(1, 420) = 420

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

= 1 / 420

= 1

Step3:

LCM(1, 774) = 774

GCD(1, 774) = ( 1 x 774 ) / 774

= 1 / 774

= 1

So, Greatest Common Divisor of 632, 615, 420, 774 is 1
