Therefore, GCD of numbers 753, 474, 81, 751 is 1

Given Input Data is 753, 474, 81, 751

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

Prime Factorization of 753 is 3 x 251

Prime Factorization of 474 is 2 x 3 x 79

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 751 is 751

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(753, 474) = 118974

GCD(753, 474) = ( 753 x 474 ) / 118974

GCD(753, 474) = 356922 / 118974

GCD(753, 474) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 81

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

LCM(3, 81) = 81

GCD(3, 81) = ( 3 x 81 ) / 81

GCD(3, 81) = 243 / 81

GCD(3, 81) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 751

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

LCM(3, 751) = 2253

GCD(3, 751) = ( 3 x 751 ) / 2253

GCD(3, 751) = 2253 / 2253

GCD(3, 751) = 1

GCD of 753, 474, 81, 751 is 1
