Greatest Common Divisior

We found the divisors of 61, 611, 770, 953 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 61, 611, 770, 953 is 1.

Therefore, GCD of numbers 61, 611, 770, 953 is 1

Given Input Data is 61, 611, 770, 953

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

Prime Factorization of 61 is 61

Prime Factorization of 611 is 13 x 47

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 953 is 953

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(61, 611) = 37271

GCD(61, 611) = ( 61 x 611 ) / 37271

GCD(61, 611) = 37271 / 37271

GCD(61, 611) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 770

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

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

GCD(1, 770) = 770 / 770

GCD(1, 770) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 953

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

LCM(1, 953) = 953

GCD(1, 953) = ( 1 x 953 ) / 953

GCD(1, 953) = 953 / 953

GCD(1, 953) = 1

GCD of 61, 611, 770, 953 is 1
