We will be focusing on factors, common factors, and prime factorization this week. A factor is a number that divides into a whole number with a remainder of 0. For example, factors of 12 would be 1 and 12, 2 and 6, and 3 and 4 (1 x 12 = 12, 2 x 6 = 12, 3 x 4 = 12).
Real-life example: Sally made 15 sugar cookies and 24 chocolate cookies for the school bake sale. She made packages of sugar cookies and packages of chocolate cookies, each with the same number of cookies. How many cookies were in each package?
Factors of 15: 1, 3, 5, 15 Common factor: 3
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24
*She could put 3 cookies in each package.
