We found the divisors of 37, 45, 20, 91 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 37, 45, 20, 91 is 1.

Therefore, GCD of numbers 37, 45, 20, 91 is 1

Given Input Data is 37, 45, 20, 91

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

Prime Factorization of 37 is 37

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 20 is 2 x 2 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(37, 45) = 1665

GCD(37, 45) = ( 37 x 45 ) / 1665

GCD(37, 45) = 1665 / 1665

GCD(37, 45) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 20

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

LCM(1, 20) = 20

GCD(1, 20) = ( 1 x 20 ) / 20

GCD(1, 20) = 20 / 20

GCD(1, 20) = 1

Step3:

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 37, 45, 20, 91 is 1
