Given numbers are 680, 422, 318, 387

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

Prime factors of 422 are 2 x 211

Prime factors of 318 are 2 x 3 x 53

Prime factors of 387 are 3 x 3 x 43

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

Given numbers are 680, 422, 318, 387

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

Apply this formula for all numbers.

Step1:

LCM(680, 422) = 143480

GCD(680, 422) = ( 680 x 422 ) / 143480

= 680 / 422

= 680

Step2:

LCM(2, 318) = 318

GCD(2, 318) = ( 2 x 318 ) / 318

= 2 / 318

= 2

Step3:

LCM(2, 387) = 774

GCD(2, 387) = ( 2 x 387 ) / 774

= 2 / 387

= 2

So, Greatest Common Divisor of 680, 422, 318, 387 is 1
