Given numbers are 668, 870, 208, 502

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

Apply this formula for all numbers.

Step1:

LCM(668, 870) = 290580

GCD(668, 870) = ( 668 x 870 ) / 290580

= 668 / 870

= 668

Step2:

LCM(2, 208) = 208

GCD(2, 208) = ( 2 x 208 ) / 208

= 2 / 208

= 2

Step3:

LCM(2, 502) = 502

GCD(2, 502) = ( 2 x 502 ) / 502

= 2 / 502

= 2

So, Greatest Common Divisor of 668, 870, 208, 502 is 2
