The prime factorization of a given positive number N is the set of prime numbers that when multiplied together give N. For instance, the prime factorization of N=8, is {2,2,2} since 2x2x2 = 8 and the prime factorization of 24 is {2,2,2,3} since 2x2x2x3 =24.

Question
Please use C
![Using this algorithm or otherwise, write a C function that computes the prime
factorisation of a number, given as input. The function should write in an
output parameter, the total number of factors. In particular, the function
should have the following prototype declaration:
void primeFactors(int n, int a[], int *num_factorsp);
n is an input parameter, corresponding to the number to be factorised.
a[] is an array, which is empty on input, but which contains all of the factors on
output from the function
num_factorsp is an output parameter that contains the total number of factors
in a[].
For example:
Test
Result
primeFactors (8, a, &numFactors);
2 2 2
primeFactors (1001,a,&numFactors); 7 11 13](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F702b401e-6f47-4214-8f6d-3d2f8fae1e96%2Fc1c7e769-6e8b-4a2e-82e5-930f01f7a34c%2Fy577afp_processed.png&w=3840&q=75)
