Given numbers are 642, 368, 403, 684

The list of prime factors of all numbers are

Prime factors of 642 are 2 x 3 x 107

Prime factors of 368 are 2 x 2 x 2 x 2 x 23

Prime factors of 403 are 13 x 31

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

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

Given numbers are 642, 368, 403, 684

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

Apply this formula for all numbers.

Step1:

LCM(642, 368) = 118128

GCD(642, 368) = ( 642 x 368 ) / 118128

= 642 / 368

= 642

Step2:

LCM(2, 403) = 806

GCD(2, 403) = ( 2 x 403 ) / 806

= 2 / 403

= 2

Step3:

LCM(1, 684) = 684

GCD(1, 684) = ( 1 x 684 ) / 684

= 1 / 684

= 1

So, Greatest Common Divisor of 642, 368, 403, 684 is 1
