Therefore, GCD of numbers 355, 515, 18, 766 is 1

Given Input Data is 355, 515, 18, 766

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

Prime Factorization of 355 is 5 x 71

Prime Factorization of 515 is 5 x 103

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 766 is 2 x 383

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(355, 515) = 36565

GCD(355, 515) = ( 355 x 515 ) / 36565

GCD(355, 515) = 182825 / 36565

GCD(355, 515) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 18

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

LCM(5, 18) = 90

GCD(5, 18) = ( 5 x 18 ) / 90

GCD(5, 18) = 90 / 90

GCD(5, 18) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 766

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

LCM(1, 766) = 766

GCD(1, 766) = ( 1 x 766 ) / 766

GCD(1, 766) = 766 / 766

GCD(1, 766) = 1

GCD of 355, 515, 18, 766 is 1
