Therefore, GCD of numbers 81, 351, 158, 763 is 1

Given Input Data is 81, 351, 158, 763

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

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

Prime Factorization of 351 is 3 x 3 x 3 x 13

Prime Factorization of 158 is 2 x 79

Prime Factorization of 763 is 7 x 109

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(81, 351) = 1053

GCD(81, 351) = ( 81 x 351 ) / 1053

GCD(81, 351) = 28431 / 1053

GCD(81, 351) = 27

Step2:

Here we consider the GCD from the above i.e. 27 as first number and the next as 158

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

LCM(27, 158) = 4266

GCD(27, 158) = ( 27 x 158 ) / 4266

GCD(27, 158) = 4266 / 4266

GCD(27, 158) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 763

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

LCM(1, 763) = 763

GCD(1, 763) = ( 1 x 763 ) / 763

GCD(1, 763) = 763 / 763

GCD(1, 763) = 1

GCD of 81, 351, 158, 763 is 1
