Therefore, GCD of numbers 140, 345, 176, 811 is 1

Given Input Data is 140, 345, 176, 811

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

Prime Factorization of 140 is 2 x 2 x 5 x 7

Prime Factorization of 345 is 3 x 5 x 23

Prime Factorization of 176 is 2 x 2 x 2 x 2 x 11

Prime Factorization of 811 is 811

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(140, 345) = 9660

GCD(140, 345) = ( 140 x 345 ) / 9660

GCD(140, 345) = 48300 / 9660

GCD(140, 345) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 176

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

LCM(5, 176) = 880

GCD(5, 176) = ( 5 x 176 ) / 880

GCD(5, 176) = 880 / 880

GCD(5, 176) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 811

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

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

GCD(1, 811) = 811 / 811

GCD(1, 811) = 1

GCD of 140, 345, 176, 811 is 1
