Steps to Calculate GCD of 171, 617, 779, 345 using LCM Formula
Given numbers are 171, 617, 779, 345
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(171, 617) = 105507
GCD(171, 617) = ( 171 x 617 ) / 105507
= 171 / 617
= 171
Step2:
LCM(1, 779) = 779
GCD(1, 779) = ( 1 x 779 ) / 779
= 1 / 779
= 1
Step3:
LCM(1, 345) = 345
GCD(1, 345) = ( 1 x 345 ) / 345
= 1 / 345
= 1
So, Greatest Common Divisor of 171, 617, 779, 345 is 1
