GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(656, 140) = 22960
GCD(656, 140) = ( 656 x 140 ) / 22960
= 656 / 140
= 656
Step2:
LCM(4, 422) = 844
GCD(4, 422) = ( 4 x 422 ) / 844
= 4 / 422
= 4
Step3:
LCM(2, 542) = 542
GCD(2, 542) = ( 2 x 542 ) / 542
= 2 / 542
= 2
So, Greatest Common Divisor of 656, 140, 422, 542 is 2
