We found the divisors of 40, 35, 75, 87 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 40, 35, 75, 87 is 1.

Therefore, GCD of numbers 40, 35, 75, 87 is 1

Given Input Data is 40, 35, 75, 87

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

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

Prime Factorization of 35 is 5 x 7

Prime Factorization of 75 is 3 x 5 x 5

Prime Factorization of 87 is 3 x 29

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(40, 35) = 280

GCD(40, 35) = ( 40 x 35 ) / 280

GCD(40, 35) = 1400 / 280

GCD(40, 35) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 75

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

LCM(5, 75) = 75

GCD(5, 75) = ( 5 x 75 ) / 75

GCD(5, 75) = 375 / 75

GCD(5, 75) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 87

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

LCM(5, 87) = 435

GCD(5, 87) = ( 5 x 87 ) / 435

GCD(5, 87) = 435 / 435

GCD(5, 87) = 1

GCD of 40, 35, 75, 87 is 1
