Just find all of the square numbers. Since they are square, that means that they have 2 of same number, otherwise it would just have pairs of numbers. Thanks!
How can you think of factors in terms of Division?
You can also think about factors in terms of division: The factors of a number include all numbers that divide evenly into that number with no remainder. Consider the number 10. Since 10 is evenly divisible by 2 and 5, you can conclude that both 2 and 5 are factors of 10.
