13 is a Prime number so only 13 and one can go into it
1, 3, 9, 13, 39, 117
13 if you include the '75', 12 if you don't.
3 numbers are factors of 121. They are 1, 11 and 121 itself.
There are 14C5 = 14*13*12*11*10/(5*4*3*2*1) = 2002
The answer is Infinity. Numbers keep going up and up and never stop. Therefore fifteen will keep going into a bigger number each time. HOWEVER, if you meant 'how many numbers go into fifteen' , the answer would be 4. Four numbers (1,3,5 and 15) go into 15.
There are infinitely many such numbers.
Only itself and one because 13 is a prime number
Four: 1 2 13 26.
1 and 13.
1, 2, 4, 13, 26, 52.
Four: 1, 2, 13, 26.
There are an infinite amount of prime numbers. Starting with 2, 3, 5, 7, 11, 13, 17 ... the numbers, as all numbers go to infinity.

The prime numbers that go into 65 are 5 and 13. This is because 65 can be factored into 5 × 13, where both 5 and 13 are prime numbers. Therefore, the prime factorization of 65 is 5 and 13.
26
1 and 13. 13 is a prime number, thus only 1 and itself can go into it.
