GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(688, 118) = 40592
GCD(688, 118) = ( 688 x 118 ) / 40592
= 688 / 118
= 688
Step2:
LCM(2, 310) = 310
GCD(2, 310) = ( 2 x 310 ) / 310
= 2 / 310
= 2
Step3:
LCM(2, 492) = 492
GCD(2, 492) = ( 2 x 492 ) / 492
= 2 / 492
= 2
So, Greatest Common Divisor of 688, 118, 310, 492 is 2
