So the Greatest Common Divisior 53, 15, 91 is 1.

Therefore, GCD of numbers 53, 15, 91 is 1

Given Input Data is 53, 15, 91

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

Prime Factorization of 53 is 53

Prime Factorization of 15 is 3 x 5

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(53, 15) = 795

GCD(53, 15) = ( 53 x 15 ) / 795

GCD(53, 15) = 795 / 795

GCD(53, 15) = 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 53, 15, 91 is 1
