GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(414, 663) = 91494
GCD(414, 663) = ( 414 x 663 ) / 91494
= 414 / 663
= 414
Step2:
LCM(3, 818) = 2454
GCD(3, 818) = ( 3 x 818 ) / 2454
= 3 / 818
= 3
Step3:
LCM(1, 816) = 816
GCD(1, 816) = ( 1 x 816 ) / 816
= 1 / 816
= 1
So, Greatest Common Divisor of 414, 663, 818, 816 is 1
