Therefore, GCD of numbers 760, 815, 18, 820 is 1

Given Input Data is 760, 815, 18, 820

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

Prime Factorization of 760 is 2 x 2 x 2 x 5 x 19

Prime Factorization of 815 is 5 x 163

Prime Factorization of 18 is 2 x 3 x 3

Prime Factorization of 820 is 2 x 2 x 5 x 41

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(760, 815) = 123880

GCD(760, 815) = ( 760 x 815 ) / 123880

GCD(760, 815) = 619400 / 123880

GCD(760, 815) = 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 820

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

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

GCD(1, 820) = 820 / 820

GCD(1, 820) = 1

GCD of 760, 815, 18, 820 is 1
