Therefore, GCD of numbers 877, 561, 956, 890 is 1

Given Input Data is 877, 561, 956, 890

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

Prime Factorization of 877 is 877

Prime Factorization of 561 is 3 x 11 x 17

Prime Factorization of 956 is 2 x 2 x 239

Prime Factorization of 890 is 2 x 5 x 89

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(877, 561) = 491997

GCD(877, 561) = ( 877 x 561 ) / 491997

GCD(877, 561) = 491997 / 491997

GCD(877, 561) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 956

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

LCM(1, 956) = 956

GCD(1, 956) = ( 1 x 956 ) / 956

GCD(1, 956) = 956 / 956

GCD(1, 956) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 890

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

LCM(1, 890) = 890

GCD(1, 890) = ( 1 x 890 ) / 890

GCD(1, 890) = 890 / 890

GCD(1, 890) = 1

GCD of 877, 561, 956, 890 is 1
