Given Input Data is 140, 525, 105, 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 525 is 3 x 5 x 5 x 7

Prime Factorization of 105 is 3 x 5 x 7

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, 525) = 2100

GCD(140, 525) = ( 140 x 525 ) / 2100

GCD(140, 525) = 73500 / 2100

GCD(140, 525) = 35

Step2:

Here we consider the GCD from the above i.e. 35 as first number and the next as 105

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

LCM(35, 105) = 105

GCD(35, 105) = ( 35 x 105 ) / 105

GCD(35, 105) = 3675 / 105

GCD(35, 105) = 35

Step3:

Here we consider the GCD from the above i.e. 35 as first number and the next as 811

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

LCM(35, 811) = 28385

GCD(35, 811) = ( 35 x 811 ) / 28385

GCD(35, 811) = 28385 / 28385

GCD(35, 811) = 1

GCD of 140, 525, 105, 811 is 1
