Steps to Calculate GCD of 209, 818, 115, 305 using LCM Formula
Given numbers are 209, 818, 115, 305
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(209, 818) = 170962
GCD(209, 818) = ( 209 x 818 ) / 170962
= 209 / 818
= 209
Step2:
LCM(1, 115) = 115
GCD(1, 115) = ( 1 x 115 ) / 115
= 1 / 115
= 1
Step3:
LCM(1, 305) = 305
GCD(1, 305) = ( 1 x 305 ) / 305
= 1 / 305
= 1
So, Greatest Common Divisor of 209, 818, 115, 305 is 1
