Steps to Calculate GCD of 129, 905, 363, 287 using LCM Formula
Given numbers are 129, 905, 363, 287
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(129, 905) = 116745
GCD(129, 905) = ( 129 x 905 ) / 116745
= 129 / 905
= 129
Step2:
LCM(1, 363) = 363
GCD(1, 363) = ( 1 x 363 ) / 363
= 1 / 363
= 1
Step3:
LCM(1, 287) = 287
GCD(1, 287) = ( 1 x 287 ) / 287
= 1 / 287
= 1
So, Greatest Common Divisor of 129, 905, 363, 287 is 1
