Steps to Calculate GCD of 638, 349, 214, 158 using LCM Formula
Given numbers are 638, 349, 214, 158
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 349) = 222662
GCD(638, 349) = ( 638 x 349 ) / 222662
= 638 / 349
= 638
Step2:
LCM(1, 214) = 214
GCD(1, 214) = ( 1 x 214 ) / 214
= 1 / 214
= 1
Step3:
LCM(1, 158) = 158
GCD(1, 158) = ( 1 x 158 ) / 158
= 1 / 158
= 1
So, Greatest Common Divisor of 638, 349, 214, 158 is 1
