Finding GCD of 245, 685, 251 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(245, 685) = 33565
GCD(245, 685) = ( 245 x 685 ) / 33565
GCD(245, 685) = 167825 / 33565
GCD(245, 685) = 5
Step2:
Here we consider the GCD from the above i.e. 5 as first number and the next as 251
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(5, 251) = 1255
GCD(5, 251) = ( 5 x 251 ) / 1255
GCD(5, 251) = 1255 / 1255
GCD(5, 251) = 1
GCD of 245, 685, 251 is 1
