Greatest Common Divisior

We found the divisors of 60, 49, 45 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 60, 49, 45 is 1.

Therefore, GCD of numbers 60, 49, 45 is 1

Given Input Data is 60, 49, 45

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

Prime Factorization of 60 is 2 x 2 x 3 x 5

Prime Factorization of 49 is 7 x 7

Prime Factorization of 45 is 3 x 3 x 5

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(60, 49) = 2940

GCD(60, 49) = ( 60 x 49 ) / 2940

GCD(60, 49) = 2940 / 2940

GCD(60, 49) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 45

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

LCM(1, 45) = 45

GCD(1, 45) = ( 1 x 45 ) / 45

GCD(1, 45) = 45 / 45

GCD(1, 45) = 1

GCD of 60, 49, 45 is 1
