Steps to Calculate GCD of 661, 663, 93, 638 using LCM Formula
Given numbers are 661, 663, 93, 638
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(661, 663) = 438243
GCD(661, 663) = ( 661 x 663 ) / 438243
= 661 / 663
= 661
Step2:
LCM(1, 93) = 93
GCD(1, 93) = ( 1 x 93 ) / 93
= 1 / 93
= 1
Step3:
LCM(1, 638) = 638
GCD(1, 638) = ( 1 x 638 ) / 638
= 1 / 638
= 1
So, Greatest Common Divisor of 661, 663, 93, 638 is 1
