  1. 1. (c) 77 has only the factors 1 and 7.
  2. 2. (b) no remainderA factor divides exactly, no remainder.
  3. 3. (c) twoExactly two: 1 and itself.
  4. 4. (a) 2 × 2 × 312 = 2 × 2 × 3.
  5. 5. A factor divides a number exactly; a multiple is built by multiplying the number.
  6. 6. Because it has only one factor (itself), not two or more.
  7. 7. A prime number has exactly two factors, 1 and itself, such as 2, 3, 5 and 7. A composite number has more than two factors, such as 6 (1, 2, 3, 6) or 9 (1, 3, 9). The number 1 is special: it has only one factor, itself, so it is neither prime nor composite. Note also that 2 is the only even prime number, since every other even number is divisible by 2 and so has more than two factors.
