Therefore, GCD of numbers 883, 861, 90, 978 is 1

Given Input Data is 883, 861, 90, 978

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

Prime Factorization of 883 is 883

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 90 is 2 x 3 x 3 x 5

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(883, 861) = 760263

GCD(883, 861) = ( 883 x 861 ) / 760263

GCD(883, 861) = 760263 / 760263

GCD(883, 861) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 90

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

LCM(1, 90) = 90

GCD(1, 90) = ( 1 x 90 ) / 90

GCD(1, 90) = 90 / 90

GCD(1, 90) = 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 883, 861, 90, 978 is 1
