13 is a Prime number so only 13 and one can go into it
1, 3, 9, 13, 39, 117
3 numbers are factors of 121. They are 1, 11 and 121 itself.
13 if you include the '75', 12 if you don't.
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.
Four: 1, 2, 13, 26.
