Therefore, GCD of numbers 441, 945, 790 is 1

Given Input Data is 441, 945, 790

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

Prime Factorization of 441 is 3 x 3 x 7 x 7

Prime Factorization of 945 is 3 x 3 x 3 x 5 x 7

Prime Factorization of 790 is 2 x 5 x 79

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(441, 945) = 6615

GCD(441, 945) = ( 441 x 945 ) / 6615

GCD(441, 945) = 416745 / 6615

GCD(441, 945) = 63

Step2:

Here we consider the GCD from the above i.e. 63 as first number and the next as 790

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

LCM(63, 790) = 49770

GCD(63, 790) = ( 63 x 790 ) / 49770

GCD(63, 790) = 49770 / 49770

GCD(63, 790) = 1

GCD of 441, 945, 790 is 1
