Steps to Calculate GCD of 878, 345, 809, 617 using LCM Formula
Given numbers are 878, 345, 809, 617
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(878, 345) = 302910
GCD(878, 345) = ( 878 x 345 ) / 302910
= 878 / 345
= 878
Step2:
LCM(1, 809) = 809
GCD(1, 809) = ( 1 x 809 ) / 809
= 1 / 809
= 1
Step3:
LCM(1, 617) = 617
GCD(1, 617) = ( 1 x 617 ) / 617
= 1 / 617
= 1
So, Greatest Common Divisor of 878, 345, 809, 617 is 1
