The prime factors of 2 are: Well, 2 has no prime factors because 2 is a prime number The prime factors of 6 are: 1, 2, 3, & 6
There are three factor pairs for 75:factor pair = 75,1factor pair = 25,3factor pair = 15,5
The factor pairs of 32 are:1 × 32 = 322 × 16 = 324 × 8 = 32The factor pairs of 44 are:1 × 44 = 442 × 22 = 444 × 11 = 44
The factor pairs of 21 are:1, 213, 7Therefore, the number 21 has two pairs of positive integer factors.
The numbers are the same as positive numbers, just the signs change. Write out the factor pairs as if the number were positive, but make one of the numbers positive and one negative. Now write the same pairs over again and reverse the signs. Negative numbers have twice as many factor pairs as positive numbers do.
