Steps to Calculate GCD of 418, 209, 905, 847 using LCM Formula
Given numbers are 418, 209, 905, 847
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(418, 209) = 418
GCD(418, 209) = ( 418 x 209 ) / 418
= 418 / 209
= 418
Step2:
LCM(209, 905) = 189145
GCD(209, 905) = ( 209 x 905 ) / 189145
= 209 / 905
= 209
Step3:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
So, Greatest Common Divisor of 418, 209, 905, 847 is 1
