Frequently asked questions
▶What is a factor?
A factor of a number is another number that divides it evenly, leaving no remainder. So 3 is a factor of 12, because 12 divided by 3 is 4 with no remainder. But 5 is not a factor of 12.
▶How do I use the factor explorer?
Pick a number and a possible divisor. The lab checks if the divisor goes in cleanly and shows the result. Try every divisor from 1 up to the number to find all the factors.
▶When are factors useful?
If you want to arrange 24 chairs in equal rows for a class function, factors of 24 tell you the row choices: 1, 2, 3, 4, 6, 8, 12 or 24. Factors help in fair sharing.
▶Did you know about factors?
1 and the number itself are always factors of any number. A number like 12 has many factors, while a prime number like 7 has only two: 1 and 7. That is what makes primes special.
