GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(637, 139) = 88543
GCD(637, 139) = ( 637 x 139 ) / 88543
= 637 / 139
= 637
Step2:
LCM(1, 686) = 686
GCD(1, 686) = ( 1 x 686 ) / 686
= 1 / 686
= 1
Step3:
LCM(1, 552) = 552
GCD(1, 552) = ( 1 x 552 ) / 552
= 1 / 552
= 1
So, Greatest Common Divisor of 637, 139, 686, 552 is 1
