Therefore, GCD of numbers 837, 981, 81, 170 is 1

Given Input Data is 837, 981, 81, 170

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

Prime Factorization of 837 is 3 x 3 x 3 x 31

Prime Factorization of 981 is 3 x 3 x 109

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 170 is 2 x 5 x 17

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(837, 981) = 91233

GCD(837, 981) = ( 837 x 981 ) / 91233

GCD(837, 981) = 821097 / 91233

GCD(837, 981) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 81

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

LCM(9, 81) = 81

GCD(9, 81) = ( 9 x 81 ) / 81

GCD(9, 81) = 729 / 81

GCD(9, 81) = 9

Step3:

Here we consider the GCD from the above i.e. 9 as first number and the next as 170

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

LCM(9, 170) = 1530

GCD(9, 170) = ( 9 x 170 ) / 1530

GCD(9, 170) = 1530 / 1530

GCD(9, 170) = 1

GCD of 837, 981, 81, 170 is 1
