GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(171, 144) = 2736
GCD(171, 144) = ( 171 x 144 ) / 2736
= 171 / 144
= 171
Step2:
LCM(9, 413) = 3717
GCD(9, 413) = ( 9 x 413 ) / 3717
= 9 / 413
= 9
Step3:
LCM(1, 639) = 639
GCD(1, 639) = ( 1 x 639 ) / 639
= 1 / 639
= 1
So, Greatest Common Divisor of 171, 144, 413, 639 is 1
