Given numbers are 656, 166, 870, 670

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

Apply this formula for all numbers.

Step1:

LCM(656, 166) = 54448

GCD(656, 166) = ( 656 x 166 ) / 54448

= 656 / 166

= 656

Step2:

LCM(2, 870) = 870

GCD(2, 870) = ( 2 x 870 ) / 870

= 2 / 870

= 2

Step3:

LCM(2, 670) = 670

GCD(2, 670) = ( 2 x 670 ) / 670

= 2 / 670

= 2

So, Greatest Common Divisor of 656, 166, 870, 670 is 2
