Given numbers are 956, 684, 42, 646

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

Apply this formula for all numbers.

Step1:

LCM(956, 684) = 163476

GCD(956, 684) = ( 956 x 684 ) / 163476

= 956 / 684

= 956

Step2:

LCM(4, 42) = 84

GCD(4, 42) = ( 4 x 42 ) / 84

= 4 / 42

= 4

Step3:

LCM(2, 646) = 646

GCD(2, 646) = ( 2 x 646 ) / 646

= 2 / 646

= 2

So, Greatest Common Divisor of 956, 684, 42, 646 is 2
