We found the divisors of 54, 62, 15, 15 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 54, 62, 15, 15 is 1.

Therefore, GCD of numbers 54, 62, 15, 15 is 1

Given Input Data is 54, 62, 15, 15

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

Prime Factorization of 54 is 2 x 3 x 3 x 3

Prime Factorization of 62 is 2 x 31

Prime Factorization of 15 is 3 x 5

Prime Factorization of 15 is 3 x 5

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(54, 62) = 1674

GCD(54, 62) = ( 54 x 62 ) / 1674

GCD(54, 62) = 3348 / 1674

GCD(54, 62) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 15

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

LCM(2, 15) = 30

GCD(2, 15) = ( 2 x 15 ) / 30

GCD(2, 15) = 30 / 30

GCD(2, 15) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 15

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

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

GCD(1, 15) = 15 / 15

GCD(1, 15) = 1

GCD of 54, 62, 15, 15 is 1
