Steps to Calculate GCD of 181, 357, 407, 128 using LCM Formula
Given numbers are 181, 357, 407, 128
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(181, 357) = 64617
GCD(181, 357) = ( 181 x 357 ) / 64617
= 181 / 357
= 181
Step2:
LCM(1, 407) = 407
GCD(1, 407) = ( 1 x 407 ) / 407
= 1 / 407
= 1
Step3:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
So, Greatest Common Divisor of 181, 357, 407, 128 is 1
