Steps to Calculate GCD of 138, 375, 665, 181 using LCM Formula
Given numbers are 138, 375, 665, 181
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(138, 375) = 17250
GCD(138, 375) = ( 138 x 375 ) / 17250
= 138 / 375
= 138
Step2:
LCM(3, 665) = 1995
GCD(3, 665) = ( 3 x 665 ) / 1995
= 3 / 665
= 3
Step3:
LCM(1, 181) = 181
GCD(1, 181) = ( 1 x 181 ) / 181
= 1 / 181
= 1
So, Greatest Common Divisor of 138, 375, 665, 181 is 1
