Greatest Common Divisior

We found the divisors of 50, 87, 66, 56 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 50, 87, 66, 56 is 1.

Therefore, GCD of numbers 50, 87, 66, 56 is 1

Given Input Data is 50, 87, 66, 56

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

Prime Factorization of 50 is 2 x 5 x 5

Prime Factorization of 87 is 3 x 29

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 56 is 2 x 2 x 2 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(50, 87) = 4350

GCD(50, 87) = ( 50 x 87 ) / 4350

GCD(50, 87) = 4350 / 4350

GCD(50, 87) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 66

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

LCM(1, 66) = 66

GCD(1, 66) = ( 1 x 66 ) / 66

GCD(1, 66) = 66 / 66

GCD(1, 66) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 56

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

LCM(1, 56) = 56

GCD(1, 56) = ( 1 x 56 ) / 56

GCD(1, 56) = 56 / 56

GCD(1, 56) = 1

GCD of 50, 87, 66, 56 is 1
