Given Input Data is 555, 795, 78, 603

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

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 795 is 3 x 5 x 53

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 603 is 3 x 3 x 67

Highest common occurrences in the given inputs are 3¹

Multiplying them we get the GCD as 3

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(555, 795) = 29415

GCD(555, 795) = ( 555 x 795 ) / 29415

GCD(555, 795) = 441225 / 29415

GCD(555, 795) = 15

Step2:

Here we consider the GCD from the above i.e. 15 as first number and the next as 78

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

LCM(15, 78) = 390

GCD(15, 78) = ( 15 x 78 ) / 390

GCD(15, 78) = 1170 / 390

GCD(15, 78) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 603

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

LCM(3, 603) = 603

GCD(3, 603) = ( 3 x 603 ) / 603

GCD(3, 603) = 1809 / 603

GCD(3, 603) = 3

GCD of 555, 795, 78, 603 is 3
