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.
So, when two negative numbers multiply, their product is a positive number (Remember the rule: minus x minus = plus). So, both the numbers in the factor pair should be either negative or positive to give a positive number as a product. For example: (-3 and -6) and (-2 and -9) form factor pairs for 18.
It is a negative number, because every pair of negative factors makes a positive, and you have 10 pairs plus one left over.
