Given numbers are 756, 644, 930, 402

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

Apply this formula for all numbers.

Step1:

LCM(756, 644) = 17388

GCD(756, 644) = ( 756 x 644 ) / 17388

= 756 / 644

= 756

Step2:

LCM(28, 930) = 13020

GCD(28, 930) = ( 28 x 930 ) / 13020

= 28 / 930

= 28

Step3:

LCM(2, 402) = 402

GCD(2, 402) = ( 2 x 402 ) / 402

= 2 / 402

= 2

So, Greatest Common Divisor of 756, 644, 930, 402 is 2
