Given numbers are 680, 684, 316, 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 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 316 are 2 x 2 x 79

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, 684, 316, 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, 684) = 116280

GCD(680, 684) = ( 680 x 684 ) / 116280

= 680 / 684

= 680

Step2:

LCM(4, 316) = 316

GCD(4, 316) = ( 4 x 316 ) / 316

= 4 / 316

= 4

Step3:

LCM(4, 387) = 1548

GCD(4, 387) = ( 4 x 387 ) / 1548

= 4 / 387

= 4

So, Greatest Common Divisor of 680, 684, 316, 387 is 1
