GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(816, 939) = 255408
GCD(816, 939) = ( 816 x 939 ) / 255408
= 816 / 939
= 816
Step2:
LCM(3, 311) = 933
GCD(3, 311) = ( 3 x 311 ) / 933
= 3 / 311
= 3
Step3:
LCM(1, 180) = 180
GCD(1, 180) = ( 1 x 180 ) / 180
= 1 / 180
= 1
So, Greatest Common Divisor of 816, 939, 311, 180 is 1
