Steps to Calculate GCD of 478, 156, 17, 166 using LCM Formula
Given numbers are 478, 156, 17, 166
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(478, 156) = 37284
GCD(478, 156) = ( 478 x 156 ) / 37284
= 478 / 156
= 478
Step2:
LCM(2, 17) = 34
GCD(2, 17) = ( 2 x 17 ) / 34
= 2 / 17
= 2
Step3:
LCM(1, 166) = 166
GCD(1, 166) = ( 1 x 166 ) / 166
= 1 / 166
= 1
So, Greatest Common Divisor of 478, 156, 17, 166 is 1
