Given Input Data is 756, 784, 261
Make a list of Prime Factors of all the given numbers initially
Prime Factorization of 756 is 2 x 2 x 3 x 3 x 3 x 7
Prime Factorization of 784 is 2 x 2 x 2 x 2 x 7 x 7
Prime Factorization of 261 is 3 x 3 x 29
The above numbers do not have any common prime factor. So GCD is 1
Finding GCD of 756, 784, 261 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(756, 784) = 21168
GCD(756, 784) = ( 756 x 784 ) / 21168
GCD(756, 784) = 592704 / 21168
GCD(756, 784) = 28
Step2:
Here we consider the GCD from the above i.e. 28 as first number and the next as 261
The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)
LCM(28, 261) = 7308
GCD(28, 261) = ( 28 x 261 ) / 7308
GCD(28, 261) = 7308 / 7308
GCD(28, 261) = 1
GCD of 756, 784, 261 is 1
