Steps to Calculate GCD of 391, 136, 151, 471 using LCM Formula
Given numbers are 391, 136, 151, 471
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 136) = 3128
GCD(391, 136) = ( 391 x 136 ) / 3128
= 391 / 136
= 391
Step2:
LCM(17, 151) = 2567
GCD(17, 151) = ( 17 x 151 ) / 2567
= 17 / 151
= 17
Step3:
LCM(1, 471) = 471
GCD(1, 471) = ( 1 x 471 ) / 471
= 1 / 471
= 1
So, Greatest Common Divisor of 391, 136, 151, 471 is 1
