Greatest Common Divisior

We found the divisors of 74, 37, 42 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 74, 37, 42 is 1.

Therefore, GCD of numbers 74, 37, 42 is 1

Given Input Data is 74, 37, 42

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

Prime Factorization of 74 is 2 x 37

Prime Factorization of 37 is 37

Prime Factorization of 42 is 2 x 3 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(74, 37) = 74

GCD(74, 37) = ( 74 x 37 ) / 74

GCD(74, 37) = 2738 / 74

GCD(74, 37) = 37

Step2:

Here we consider the GCD from the above i.e. 37 as first number and the next as 42

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

LCM(37, 42) = 1554

GCD(37, 42) = ( 37 x 42 ) / 1554

GCD(37, 42) = 1554 / 1554

GCD(37, 42) = 1

GCD of 74, 37, 42 is 1
