Therefore, GCD of numbers 805, 145, 100, 762 is 1

Given Input Data is 805, 145, 100, 762

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

Prime Factorization of 805 is 5 x 7 x 23

Prime Factorization of 145 is 5 x 29

Prime Factorization of 100 is 2 x 2 x 5 x 5

Prime Factorization of 762 is 2 x 3 x 127

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(805, 145) = 23345

GCD(805, 145) = ( 805 x 145 ) / 23345

GCD(805, 145) = 116725 / 23345

GCD(805, 145) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 100

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

LCM(5, 100) = 100

GCD(5, 100) = ( 5 x 100 ) / 100

GCD(5, 100) = 500 / 100

GCD(5, 100) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 762

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

LCM(5, 762) = 3810

GCD(5, 762) = ( 5 x 762 ) / 3810

GCD(5, 762) = 3810 / 3810

GCD(5, 762) = 1

GCD of 805, 145, 100, 762 is 1
