GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 112) = 4816
GCD(688, 112) = ( 688 x 112 ) / 4816
= 688 / 112
= 688
Step2:
LCM(16, 470) = 3760
GCD(16, 470) = ( 16 x 470 ) / 3760
= 16 / 470
= 16
Step3:
LCM(2, 981) = 1962
GCD(2, 981) = ( 2 x 981 ) / 1962
= 2 / 981
= 2
So, Greatest Common Divisor of 688, 112, 470, 981 is 1
