Ashford MAT 126 (Survey of Mathimatical Methods)Week 1 DQ & Quiz

Ashford MAT 126 Week 1 DQ 1

All numbers in our real number system are the product of prime numbers. Complete the following steps for this discussion:

1. List the ages of two people in your life, one older than you and one younger than you. It would be best if the younger person was 15 years of age or younger.
2. Find the prime factorizations of your age and the other two persons’ ages. Show your work listed by name and age. Make sure your work is clear and concise.
3. Find the LCM and the GCF for each set of numbers. Again, be clear and concise. Explain or show how you arrived at your answers.
4. In your own words, explain the meaning of your calculated LCM and GCF for the ages you selected.  Do not explain how you got the numbers; rather explain the meaning of the numbers. Be specific to your numbers; do not give generic definitions.
5. Respond to at least two of your classmates’ postings. Did your classmates calculate the LCM and GCF correctly? Are their interpretations correctly applied to the ages?
