Steps to Calculate GCD of 165, 438, 203, 401 using LCM Formula
Given numbers are 165, 438, 203, 401
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(165, 438) = 24090
GCD(165, 438) = ( 165 x 438 ) / 24090
= 165 / 438
= 165
Step2:
LCM(3, 203) = 609
GCD(3, 203) = ( 3 x 203 ) / 609
= 3 / 203
= 3
Step3:
LCM(1, 401) = 401
GCD(1, 401) = ( 1 x 401 ) / 401
= 1 / 401
= 1
So, Greatest Common Divisor of 165, 438, 203, 401 is 1
