Steps to Calculate GCD of 238, 139, 361, 147 using LCM Formula
Given numbers are 238, 139, 361, 147
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(238, 139) = 33082
GCD(238, 139) = ( 238 x 139 ) / 33082
= 238 / 139
= 238
Step2:
LCM(1, 361) = 361
GCD(1, 361) = ( 1 x 361 ) / 361
= 1 / 361
= 1
Step3:
LCM(1, 147) = 147
GCD(1, 147) = ( 1 x 147 ) / 147
= 1 / 147
= 1
So, Greatest Common Divisor of 238, 139, 361, 147 is 1
