GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(628, 116) = 18212
GCD(628, 116) = ( 628 x 116 ) / 18212
= 628 / 116
= 628
Step2:
LCM(4, 656) = 656
GCD(4, 656) = ( 4 x 656 ) / 656
= 4 / 656
= 4
Step3:
LCM(4, 426) = 852
GCD(4, 426) = ( 4 x 426 ) / 852
= 4 / 426
= 4
So, Greatest Common Divisor of 628, 116, 656, 426 is 2
