Given numbers are 721, 477, 122, 443
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(721, 477) = 343917
GCD(721, 477) = ( 721 x 477 ) / 343917
= 721 / 477
= 721
Step2:
LCM(1, 122) = 122
GCD(1, 122) = ( 1 x 122 ) / 122
= 1 / 122
= 1
Step3:
LCM(1, 443) = 443
GCD(1, 443) = ( 1 x 443 ) / 443
= 1 / 443
= 1
So, Greatest Common Divisor of 721, 477, 122, 443 is 1
