Given numbers are 387, 480, 332, 638

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 480 are 2 x 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 332 are 2 x 2 x 83

Prime factors of 638 are 2 x 11 x 29

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

Given numbers are 387, 480, 332, 638

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

Apply this formula for all numbers.

Step1:

LCM(387, 480) = 61920

GCD(387, 480) = ( 387 x 480 ) / 61920

= 387 / 480

= 387

Step2:

LCM(3, 332) = 996

GCD(3, 332) = ( 3 x 332 ) / 996

= 3 / 332

= 3

Step3:

LCM(1, 638) = 638

GCD(1, 638) = ( 1 x 638 ) / 638

= 1 / 638

= 1

So, Greatest Common Divisor of 387, 480, 332, 638 is 1
