Steps to Calculate GCD of 809, 742, 643, 305 using LCM Formula
Given numbers are 809, 742, 643, 305
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(809, 742) = 600278
GCD(809, 742) = ( 809 x 742 ) / 600278
= 809 / 742
= 809
Step2:
LCM(1, 643) = 643
GCD(1, 643) = ( 1 x 643 ) / 643
= 1 / 643
= 1
Step3:
LCM(1, 305) = 305
GCD(1, 305) = ( 1 x 305 ) / 305
= 1 / 305
= 1
So, Greatest Common Divisor of 809, 742, 643, 305 is 1
