Finding GCD of 485, 605, 840 using LCM Formula
Step1:
Let's calculate the GCD of first two numbers
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(485, 605) = 58685
GCD(485, 605) = ( 485 x 605 ) / 58685
GCD(485, 605) = 293425 / 58685
GCD(485, 605) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 840
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 840) = 840
GCD(5, 840) = ( 5 x 840 ) / 840
GCD(5, 840) = 4200 / 840
GCD(5, 840) = 5
GCD of 485, 605, 840 is 5
