Steps to Calculate GCD of 638, 481, 481, 351 using LCM Formula
Given numbers are 638, 481, 481, 351
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 481) = 306878
GCD(638, 481) = ( 638 x 481 ) / 306878
= 638 / 481
= 638
Step2:
LCM(1, 481) = 481
GCD(1, 481) = ( 1 x 481 ) / 481
= 1 / 481
= 1
Step3:
LCM(1, 351) = 351
GCD(1, 351) = ( 1 x 351 ) / 351
= 1 / 351
= 1
So, Greatest Common Divisor of 638, 481, 481, 351 is 1
