GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(818, 268) = 109612
GCD(818, 268) = ( 818 x 268 ) / 109612
= 818 / 268
= 818
Step2:
LCM(2, 430) = 430
GCD(2, 430) = ( 2 x 430 ) / 430
= 2 / 430
= 2
Step3:
LCM(2, 654) = 654
GCD(2, 654) = ( 2 x 654 ) / 654
= 2 / 654
= 2
So, Greatest Common Divisor of 818, 268, 430, 654 is 2
