Given numbers are 387, 232, 484, 640

The list of prime factors of all numbers are

Prime factors of 387 are 3 x 3 x 43

Prime factors of 232 are 2 x 2 x 2 x 29

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

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

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

Given numbers are 387, 232, 484, 640

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

Apply this formula for all numbers.

Step1:

LCM(387, 232) = 89784

GCD(387, 232) = ( 387 x 232 ) / 89784

= 387 / 232

= 387

Step2:

LCM(1, 484) = 484

GCD(1, 484) = ( 1 x 484 ) / 484

= 1 / 484

= 1

Step3:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

So, Greatest Common Divisor of 387, 232, 484, 640 is 1
