Greatest Common Divisior

We found the divisors of 61, 68, 98 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 61, 68, 98 is 1.

Therefore, GCD of numbers 61, 68, 98 is 1

Given Input Data is 61, 68, 98

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

Prime Factorization of 61 is 61

Prime Factorization of 68 is 2 x 2 x 17

Prime Factorization of 98 is 2 x 7 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(61, 68) = 4148

GCD(61, 68) = ( 61 x 68 ) / 4148

GCD(61, 68) = 4148 / 4148

GCD(61, 68) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 98

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

LCM(1, 98) = 98

GCD(1, 98) = ( 1 x 98 ) / 98

GCD(1, 98) = 98 / 98

GCD(1, 98) = 1

GCD of 61, 68, 98 is 1
