Given Input Data is 55, 555, 595, 640

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

Prime Factorization of 55 is 5 x 11

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 595 is 5 x 7 x 17

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Highest common occurrences in the given inputs are 5¹

Multiplying them we get the GCD as 5

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(55, 555) = 6105

GCD(55, 555) = ( 55 x 555 ) / 6105

GCD(55, 555) = 30525 / 6105

GCD(55, 555) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 595

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

LCM(5, 595) = 595

GCD(5, 595) = ( 5 x 595 ) / 595

GCD(5, 595) = 2975 / 595

GCD(5, 595) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 640

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

LCM(5, 640) = 640

GCD(5, 640) = ( 5 x 640 ) / 640

GCD(5, 640) = 3200 / 640

GCD(5, 640) = 5

GCD of 55, 555, 595, 640 is 5
