Given Input Data is 803, 143, 77, 761

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

Prime Factorization of 803 is 11 x 73

Prime Factorization of 143 is 11 x 13

Prime Factorization of 77 is 7 x 11

Prime Factorization of 761 is 761

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(803, 143) = 10439

GCD(803, 143) = ( 803 x 143 ) / 10439

GCD(803, 143) = 114829 / 10439

GCD(803, 143) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 77

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

LCM(11, 77) = 77

GCD(11, 77) = ( 11 x 77 ) / 77

GCD(11, 77) = 847 / 77

GCD(11, 77) = 11

Step3:

Here we consider the GCD from the above i.e. 11 as first number and the next as 761

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

LCM(11, 761) = 8371

GCD(11, 761) = ( 11 x 761 ) / 8371

GCD(11, 761) = 8371 / 8371

GCD(11, 761) = 1

GCD of 803, 143, 77, 761 is 1
