Therefore, GCD of numbers 325, 215, 643, 763 is 1

Given Input Data is 325, 215, 643, 763

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 325 is 5 x 5 x 13

Prime Factorization of 215 is 5 x 43

Prime Factorization of 643 is 643

Prime Factorization of 763 is 7 x 109

The above numbers do not have any common prime factor. So GCD is 1

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(325, 215) = 13975

GCD(325, 215) = ( 325 x 215 ) / 13975

GCD(325, 215) = 69875 / 13975

GCD(325, 215) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 643

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(5, 643) = 3215

GCD(5, 643) = ( 5 x 643 ) / 3215

GCD(5, 643) = 3215 / 3215

GCD(5, 643) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 763

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

GCD(1, 763) = 763 / 763

GCD(1, 763) = 1

GCD of 325, 215, 643, 763 is 1
