We found the divisors of 32, 91, 87, 55 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 32, 91, 87, 55 is 1.

Therefore, GCD of numbers 32, 91, 87, 55 is 1

Given Input Data is 32, 91, 87, 55

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

Prime Factorization of 32 is 2 x 2 x 2 x 2 x 2

Prime Factorization of 91 is 7 x 13

Prime Factorization of 87 is 3 x 29

Prime Factorization of 55 is 5 x 11

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(32, 91) = 2912

GCD(32, 91) = ( 32 x 91 ) / 2912

GCD(32, 91) = 2912 / 2912

GCD(32, 91) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 87

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

LCM(1, 87) = 87

GCD(1, 87) = ( 1 x 87 ) / 87

GCD(1, 87) = 87 / 87

GCD(1, 87) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 55

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

LCM(1, 55) = 55

GCD(1, 55) = ( 1 x 55 ) / 55

GCD(1, 55) = 55 / 55

GCD(1, 55) = 1

GCD of 32, 91, 87, 55 is 1
