1, 73

Greatest Common Divisior

We found the divisors of 62, 72, 40, 73 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 62, 72, 40, 73 is 1.

Therefore, GCD of numbers 62, 72, 40, 73 is 1

Given Input Data is 62, 72, 40, 73

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

Prime Factorization of 62 is 2 x 31

Prime Factorization of 72 is 2 x 2 x 2 x 3 x 3

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 73 is 73

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(62, 72) = 2232

GCD(62, 72) = ( 62 x 72 ) / 2232

GCD(62, 72) = 4464 / 2232

GCD(62, 72) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 40

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

LCM(2, 40) = 40

GCD(2, 40) = ( 2 x 40 ) / 40

GCD(2, 40) = 80 / 40

GCD(2, 40) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 73

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

LCM(2, 73) = 146

GCD(2, 73) = ( 2 x 73 ) / 146

GCD(2, 73) = 146 / 146

GCD(2, 73) = 1

GCD of 62, 72, 40, 73 is 1
