Therefore, GCD of numbers 775, 985, 757, 978 is 1

Given Input Data is 775, 985, 757, 978

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

Prime Factorization of 775 is 5 x 5 x 31

Prime Factorization of 985 is 5 x 197

Prime Factorization of 757 is 757

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(775, 985) = 152675

GCD(775, 985) = ( 775 x 985 ) / 152675

GCD(775, 985) = 763375 / 152675

GCD(775, 985) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 757

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

LCM(5, 757) = 3785

GCD(5, 757) = ( 5 x 757 ) / 3785

GCD(5, 757) = 3785 / 3785

GCD(5, 757) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 978

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

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

GCD(1, 978) = 978 / 978

GCD(1, 978) = 1

GCD of 775, 985, 757, 978 is 1
