So the Greatest Common Divisior 691, 495, 70 is 1.

Therefore, GCD of numbers 691, 495, 70 is 1

Given Input Data is 691, 495, 70

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

Prime Factorization of 691 is 691

Prime Factorization of 495 is 3 x 3 x 5 x 11

Prime Factorization of 70 is 2 x 5 x 7

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(691, 495) = 342045

GCD(691, 495) = ( 691 x 495 ) / 342045

GCD(691, 495) = 342045 / 342045

GCD(691, 495) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 70

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

LCM(1, 70) = 70

GCD(1, 70) = ( 1 x 70 ) / 70

GCD(1, 70) = 70 / 70

GCD(1, 70) = 1

GCD of 691, 495, 70 is 1
