Therefore, GCD of numbers 991, 288, 62, 458 is 1

Given Input Data is 991, 288, 62, 458

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

Prime Factorization of 991 is 991

Prime Factorization of 288 is 2 x 2 x 2 x 2 x 2 x 3 x 3

Prime Factorization of 62 is 2 x 31

Prime Factorization of 458 is 2 x 229

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(991, 288) = 285408

GCD(991, 288) = ( 991 x 288 ) / 285408

GCD(991, 288) = 285408 / 285408

GCD(991, 288) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 62

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

LCM(1, 62) = 62

GCD(1, 62) = ( 1 x 62 ) / 62

GCD(1, 62) = 62 / 62

GCD(1, 62) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 458

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

LCM(1, 458) = 458

GCD(1, 458) = ( 1 x 458 ) / 458

GCD(1, 458) = 458 / 458

GCD(1, 458) = 1

GCD of 991, 288, 62, 458 is 1
