4th Grade Math 5.4, Factors & Multiples

Factors and multiples are related. A factor times a factor is a product, and the product is a multiple of either factor. We can make lists of multiples as products of a number and a counting number. And video 5.2 we learned the rules for divisibility. If a number is divisible by n, then n is a factor of the number. We review the meaning of the word variable. Aside from using divisibility rules, we can list multiples of a number to see if a number is in the list. We can also use division to find if a number is a factor of another number. A multiple of a number can be found by skip-counting by that number. A common multiple is a multiple of two or more numbers. We write yes or no if a number is a factor of a given number. We write yes or no if a number is a multiple of a given number. We write an unknown number in a list of multiples. We solve a word problem involving common multiples and a calendar. We complete a Venn Diagram for factors of a given number and the first 12 multiples of another number.
