Steps to Calculate GCD of 687, 435, 328, 166 using LCM Formula
Given numbers are 687, 435, 328, 166
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(687, 435) = 99615
GCD(687, 435) = ( 687 x 435 ) / 99615
= 687 / 435
= 687
Step2:
LCM(3, 328) = 984
GCD(3, 328) = ( 3 x 328 ) / 984
= 3 / 328
= 3
Step3:
LCM(1, 166) = 166
GCD(1, 166) = ( 1 x 166 ) / 166
= 1 / 166
= 1
So, Greatest Common Divisor of 687, 435, 328, 166 is 1
