GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 392) = 250488
GCD(639, 392) = ( 639 x 392 ) / 250488
= 639 / 392
= 639
Step2:
LCM(1, 893) = 893
GCD(1, 893) = ( 1 x 893 ) / 893
= 1 / 893
= 1
Step3:
LCM(1, 679) = 679
GCD(1, 679) = ( 1 x 679 ) / 679
= 1 / 679
= 1
So, Greatest Common Divisor of 639, 392, 893, 679 is 1
