GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(738, 646) = 238374
GCD(738, 646) = ( 738 x 646 ) / 238374
= 738 / 646
= 738
Step2:
LCM(2, 961) = 1922
GCD(2, 961) = ( 2 x 961 ) / 1922
= 2 / 961
= 2
Step3:
LCM(1, 618) = 618
GCD(1, 618) = ( 1 x 618 ) / 618
= 1 / 618
= 1
So, Greatest Common Divisor of 738, 646, 961, 618 is 1
