So the Greatest Common Divisior 24, 87, 77 is 1.

Therefore, GCD of numbers 24, 87, 77 is 1

Given Input Data is 24, 87, 77

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

Prime Factorization of 24 is 2 x 2 x 2 x 3

Prime Factorization of 87 is 3 x 29

Prime Factorization of 77 is 7 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(24, 87) = 696

GCD(24, 87) = ( 24 x 87 ) / 696

GCD(24, 87) = 2088 / 696

GCD(24, 87) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 77

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

LCM(3, 77) = 231

GCD(3, 77) = ( 3 x 77 ) / 231

GCD(3, 77) = 231 / 231

GCD(3, 77) = 1

GCD of 24, 87, 77 is 1
