GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(479, 688) = 329552
GCD(479, 688) = ( 479 x 688 ) / 329552
= 479 / 688
= 479
Step2:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
Step3:
LCM(1, 791) = 791
GCD(1, 791) = ( 1 x 791 ) / 791
= 1 / 791
= 1
So, Greatest Common Divisor of 479, 688, 646, 791 is 1
