Given Input Data is 885, 655, 978

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

Prime Factorization of 885 is 3 x 5 x 59

Prime Factorization of 655 is 5 x 131

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(885, 655) = 115935

GCD(885, 655) = ( 885 x 655 ) / 115935

GCD(885, 655) = 579675 / 115935

GCD(885, 655) = 5

Step2:

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 885, 655, 978 is 1
