Given numbers are 721, 618, 502, 649
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 618) = 4326
GCD(721, 618) = ( 721 x 618 ) / 4326
= 721 / 618
= 721
Step2:
LCM(103, 502) = 51706
GCD(103, 502) = ( 103 x 502 ) / 51706
= 103 / 502
= 103
Step3:
LCM(1, 649) = 649
GCD(1, 649) = ( 1 x 649 ) / 649
= 1 / 649
= 1
So, Greatest Common Divisor of 721, 618, 502, 649 is 1
