Given Input Data is 570, 745, 55, 978

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

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 745 is 5 x 149

Prime Factorization of 55 is 5 x 11

Prime Factorization of 978 is 2 x 3 x 163

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(570, 745) = 84930

GCD(570, 745) = ( 570 x 745 ) / 84930

GCD(570, 745) = 424650 / 84930

GCD(570, 745) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 55

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

LCM(5, 55) = 55

GCD(5, 55) = ( 5 x 55 ) / 55

GCD(5, 55) = 275 / 55

GCD(5, 55) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 978

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

LCM(5, 978) = 4890

GCD(5, 978) = ( 5 x 978 ) / 4890

GCD(5, 978) = 4890 / 4890

GCD(5, 978) = 1

GCD of 570, 745, 55, 978 is 1
