The document discusses the greatest common factor (GCF) and least common multiple (LCM) of numbers. It provides examples of using the ladder method to find the GCF of various number pairs and sets, as well as using the ladder method to find the LCM of number pairs. The ladder method involves dividing the numbers by their common factors until only prime factors remain.

1. GCF and LCMGreatest Common Factor and Least Common Multiple

2. LCM and GCFLeast Common Multiple (LCM)-Of all common multiples of two or more numbers, the smallest multiple.Greatest Common Factor(GCF)- The greatest common factor of two or more nonzero whole numbers.

3. Using the Ladders methodFind the GCF of 16 and 2016202÷2÷22108GCF=2(2)=4 ÷2÷245

4. Using the Ladder methodFind the GCF of 24, 40, & 602440244÷4÷4÷421066GCF=4(2) = 8 ÷2÷2÷2353

5. Using the Ladder methodFind the GCF of 28 and 4228422GCF=2(7)=14 ÷2÷272114÷7÷723

6. Using the Ladder methodFind the LCM of 225 and 380LCM=5(9)(5)(8) =18002253605÷5÷597245÷9÷958

7. Using the Ladder methodFind the LCM of 25 and 35LCM=5(5)(7) = 17525355÷5÷575

8. Using the Ladder methodFind the LCM of 24, 40, & 602440244÷4÷4÷421066÷2÷2÷23353LCM=4(2)(3) (1)(5)(1)= 120÷3÷3115
