Greatest Common Divisior

We found the divisors of 49, 61, 91 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 49, 61, 91 is 1.

Therefore, GCD of numbers 49, 61, 91 is 1

Given Input Data is 49, 61, 91

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

Prime Factorization of 49 is 7 x 7

Prime Factorization of 61 is 61

Prime Factorization of 91 is 7 x 13

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(49, 61) = 2989

GCD(49, 61) = ( 49 x 61 ) / 2989

GCD(49, 61) = 2989 / 2989

GCD(49, 61) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 91

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

LCM(1, 91) = 91

GCD(1, 91) = ( 1 x 91 ) / 91

GCD(1, 91) = 91 / 91

GCD(1, 91) = 1

GCD of 49, 61, 91 is 1
