Given Input Data is 820, 968, 809, 469

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

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

Prime Factorization of 968 is 2 x 2 x 2 x 11 x 11

Prime Factorization of 809 is 809

Prime Factorization of 469 is 7 x 67

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(820, 968) = 198440

GCD(820, 968) = ( 820 x 968 ) / 198440

GCD(820, 968) = 793760 / 198440

GCD(820, 968) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 809

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

LCM(4, 809) = 3236

GCD(4, 809) = ( 4 x 809 ) / 3236

GCD(4, 809) = 3236 / 3236

GCD(4, 809) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 469

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

LCM(1, 469) = 469

GCD(1, 469) = ( 1 x 469 ) / 469

GCD(1, 469) = 469 / 469

GCD(1, 469) = 1

GCD of 820, 968, 809, 469 is 1
