We found the divisors of 82, 60, 55, 87 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 82, 60, 55, 87 is 1.

Therefore, GCD of numbers 82, 60, 55, 87 is 1

Given Input Data is 82, 60, 55, 87

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

Prime Factorization of 82 is 2 x 41

Prime Factorization of 60 is 2 x 2 x 3 x 5

Prime Factorization of 55 is 5 x 11

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(82, 60) = 2460

GCD(82, 60) = ( 82 x 60 ) / 2460

GCD(82, 60) = 4920 / 2460

GCD(82, 60) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 55

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

LCM(2, 55) = 110

GCD(2, 55) = ( 2 x 55 ) / 110

GCD(2, 55) = 110 / 110

GCD(2, 55) = 1

Step3:

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

GCD of 82, 60, 55, 87 is 1
