How can you factor 111?

Answer 1

The number 111 has four positive factors: 1, 3, 37, 111.The easiest way to factor a number is to start with 1 and start checking each number higher to see if it will go into the number:

1 x 111 = 111

3 x 37 = 111

No other numbers go into 111, so these are the only factors.
