Therefore, GCD of numbers 603, 172, 54, 656 is 1

Given Input Data is 603, 172, 54, 656

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

Prime Factorization of 603 is 3 x 3 x 67

Prime Factorization of 172 is 2 x 2 x 43

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

Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41

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(603, 172) = 103716

GCD(603, 172) = ( 603 x 172 ) / 103716

GCD(603, 172) = 103716 / 103716

GCD(603, 172) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 54

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

LCM(1, 54) = 54

GCD(1, 54) = ( 1 x 54 ) / 54

GCD(1, 54) = 54 / 54

GCD(1, 54) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 656

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

LCM(1, 656) = 656

GCD(1, 656) = ( 1 x 656 ) / 656

GCD(1, 656) = 656 / 656

GCD(1, 656) = 1

GCD of 603, 172, 54, 656 is 1
