Greatest Common Divisior

We found the divisors of 60, 66, 88, 55 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 60, 66, 88, 55 is 1.

Therefore, GCD of numbers 60, 66, 88, 55 is 1

Given Input Data is 60, 66, 88, 55

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

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

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 88 is 2 x 2 x 2 x 11

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(60, 66) = 660

GCD(60, 66) = ( 60 x 66 ) / 660

GCD(60, 66) = 3960 / 660

GCD(60, 66) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 88

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

LCM(6, 88) = 264

GCD(6, 88) = ( 6 x 88 ) / 264

GCD(6, 88) = 528 / 264

GCD(6, 88) = 2

Step3:

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

GCD of 60, 66, 88, 55 is 1
