Steps to Calculate GCD of 638, 150, 19, 478 using LCM Formula
Given numbers are 638, 150, 19, 478
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 150) = 47850
GCD(638, 150) = ( 638 x 150 ) / 47850
= 638 / 150
= 638
Step2:
LCM(2, 19) = 38
GCD(2, 19) = ( 2 x 19 ) / 38
= 2 / 19
= 2
Step3:
LCM(1, 478) = 478
GCD(1, 478) = ( 1 x 478 ) / 478
= 1 / 478
= 1
So, Greatest Common Divisor of 638, 150, 19, 478 is 1
