Therefore, GCD of numbers 897, 870, 51, 983 is 1

Given Input Data is 897, 870, 51, 983

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

Prime Factorization of 897 is 3 x 13 x 23

Prime Factorization of 870 is 2 x 3 x 5 x 29

Prime Factorization of 51 is 3 x 17

Prime Factorization of 983 is 983

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(897, 870) = 260130

GCD(897, 870) = ( 897 x 870 ) / 260130

GCD(897, 870) = 780390 / 260130

GCD(897, 870) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 51

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

LCM(3, 51) = 51

GCD(3, 51) = ( 3 x 51 ) / 51

GCD(3, 51) = 153 / 51

GCD(3, 51) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 983

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

LCM(3, 983) = 2949

GCD(3, 983) = ( 3 x 983 ) / 2949

GCD(3, 983) = 2949 / 2949

GCD(3, 983) = 1

GCD of 897, 870, 51, 983 is 1
