Steps to Calculate GCD of 191, 138, 622, 178 using LCM Formula
Given numbers are 191, 138, 622, 178
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(191, 138) = 26358
GCD(191, 138) = ( 191 x 138 ) / 26358
= 191 / 138
= 191
Step2:
LCM(1, 622) = 622
GCD(1, 622) = ( 1 x 622 ) / 622
= 1 / 622
= 1
Step3:
LCM(1, 178) = 178
GCD(1, 178) = ( 1 x 178 ) / 178
= 1 / 178
= 1
So, Greatest Common Divisor of 191, 138, 622, 178 is 1
