Highest Common Factor

Sheet 9

Find the highest common factor of these numbers:

1. 30, 12 - 6
2. 3, 2 -1
3. 10, 60 - 10
4. 2, 3 - 1
5. 15, 20 - 5
6. 6, 24 - 6
7. 5, 30 - 5
8. 20, 3 - 1
9. 8,2 - 2
10. 3, 60 - 3

This is my DLO on Highest Common Factors. To figure these out, we had to compare the two numbers and find out which numbers they could be divided by and see which numbers were the same.
