We found the divisors of 53, 78, 45 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 53, 78, 45 is 1.

Therefore, GCD of numbers 53, 78, 45 is 1

Given Input Data is 53, 78, 45

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

Prime Factorization of 53 is 53

Prime Factorization of 78 is 2 x 3 x 13

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(53, 78) = 4134

GCD(53, 78) = ( 53 x 78 ) / 4134

GCD(53, 78) = 4134 / 4134

GCD(53, 78) = 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 53, 78, 45 is 1
