Finding GCD of 90, 75, 85 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(90, 75) = 450
GCD(90, 75) = ( 90 x 75 ) / 450
GCD(90, 75) = 6750 / 450
GCD(90, 75) = 15
Step2:
Here we consider the GCD from the above i.e. 15 as first number and the next as 85
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(15, 85) = 255
GCD(15, 85) = ( 15 x 85 ) / 255
GCD(15, 85) = 1275 / 255
GCD(15, 85) = 5
GCD of 90, 75, 85 is 5
