Steps to Calculate GCD of 381, 658, 311, 459 using LCM Formula
Given numbers are 381, 658, 311, 459
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(381, 658) = 250698
GCD(381, 658) = ( 381 x 658 ) / 250698
= 381 / 658
= 381
Step2:
LCM(1, 311) = 311
GCD(1, 311) = ( 1 x 311 ) / 311
= 1 / 311
= 1
Step3:
LCM(1, 459) = 459
GCD(1, 459) = ( 1 x 459 ) / 459
= 1 / 459
= 1
So, Greatest Common Divisor of 381, 658, 311, 459 is 1
