Given numbers are 387, 662, 422, 480

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 662 are 2 x 331

Prime factors of 422 are 2 x 211

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

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

Given numbers are 387, 662, 422, 480

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

Apply this formula for all numbers.

Step1:

LCM(387, 662) = 256194

GCD(387, 662) = ( 387 x 662 ) / 256194

= 387 / 662

= 387

Step2:

LCM(1, 422) = 422

GCD(1, 422) = ( 1 x 422 ) / 422

= 1 / 422

= 1

Step3:

LCM(1, 480) = 480

GCD(1, 480) = ( 1 x 480 ) / 480

= 1 / 480

= 1

So, Greatest Common Divisor of 387, 662, 422, 480 is 1
