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

Apply this formula for all numbers.

Step1:

LCM(432, 836) = 90288

GCD(432, 836) = ( 432 x 836 ) / 90288

= 432 / 836

= 432

Step2:

LCM(4, 786) = 1572

GCD(4, 786) = ( 4 x 786 ) / 1572

= 4 / 786

= 4

Step3:

LCM(2, 646) = 646

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

= 2 / 646

= 2

So, Greatest Common Divisor of 432, 836, 786, 646 is 2
