GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(657, 991) = 651087
GCD(657, 991) = ( 657 x 991 ) / 651087
= 657 / 991
= 657
Step2:
LCM(1, 752) = 752
GCD(1, 752) = ( 1 x 752 ) / 752
= 1 / 752
= 1
Step3:
LCM(1, 477) = 477
GCD(1, 477) = ( 1 x 477 ) / 477
= 1 / 477
= 1
So, Greatest Common Divisor of 657, 991, 752, 477 is 1
