Given numbers are 708, 420, 656, 681
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(708, 420) = 24780
GCD(708, 420) = ( 708 x 420 ) / 24780
= 708 / 420
= 708
Step2:
LCM(12, 656) = 1968
GCD(12, 656) = ( 12 x 656 ) / 1968
= 12 / 656
= 12
Step3:
LCM(4, 681) = 2724
GCD(4, 681) = ( 4 x 681 ) / 2724
= 4 / 681
= 4
So, Greatest Common Divisor of 708, 420, 656, 681 is 1
