August 13, 2015 Problem 1.1 Focus Question: How can you find all the factors (or divisors) of a number? Vocabulary to consider: 1. Divisor - a number that divides a given number leaving a remainder of zero 2. Factor - one of two or more whole numbers that are multiplied to get a product 3. Proper Factors - all the factors of a number, except the number itself 1 August 13, 2015 Problem 1.1 Notes 1. Identify a divisor of 20 and explain WHY it is a divisor of 20: 4; the quotient of 20 and 4 equals 5 with a remainder of zero Identify 2 factors of 52 and explain WHY they are factors of 52: 2 and 26; the product of 2 and 26 equals 52 Identify the proper factors 16: 1, 2, 4 and 8 Launch- What factors can you multiply to get a product of 10? 1, 2, 5 and 10 What numbers divide 10 evenly? 1, 2, 5 and 10 How are these two lists related? the same 2 August 13, 2015 The Factor Game 3 August 13, 2015 Play the Factor Game several times with a partner. A 1. How can you determine whether one number is a factor of another number? You test the number by dividing it into the original number. If there is a whole number answer, then the number is a factor of the original number. 2. If you know a factor of a number, can you find another factor? Explain. You divide the known factor into the original number. The quotient is another factor of the number. 3. Make a list of the factors of 18. Then make a list of the divisors of 18. Are the factors of a number also divisors of the number? Explain your reasoning. Factors: 1, 2, 3, 6, 9 and 18 Divisors: 1, 2, 3, 6, 9 and 18 They are the same. In each case, you can find a whole number that you can multiply by the factor or divisor and get the product 18 B Give an example of a number that has many factors. Then give an example of a number that has few factors. Many: 24; 1, 2, 3, 4, 6, 8, 12 and 24 Few: 7; 1 and 7 C How do you know when you have found all of the factors of a number? You know that you have found all of the factors of a number when there are no numbers left that are less than the original number and that divide evenly into the original number. 4 August 13, 2015 In your classwork section: Complete problems #1-7 Answer all questions in complete sentences!!! 5
