To find the factors of 80, we need to determine which numbers divide evenly into 80. One way to approach this is by listing all the numbers and checking if they divide 80 without leaving a remainder.

Start with 1: 80 ÷ 1 = 80. Since 1 divides evenly into 80, 1 is a factor of 80.

Next, try 2: 80 ÷ 2 = 40. Again, 2 divides evenly into 80, making 2 a factor of 80.

Continue this process for larger numbers until you reach the square root of 80 (approximately 8.94). Checking numbers larger than the square root is unnecessary since factors come in pairs.

Now, let's continue listing the factors:

3 does not divide evenly into 80 (80 ÷ 3 = 26.67).
4 does divide evenly into 80 (80 ÷ 4 = 20).
5 divides evenly into 80 (80 ÷ 5 = 16).
6 does not divide evenly into 80 (80 ÷ 6 = 13.33).
7 does not divide evenly into 80 (80 ÷ 7 = 11.43).
8 divides evenly into 80 (80 ÷ 8 = 10).

At this point, we have found all the factors of 80 that are less than its square root. The pairs of factors are 1 and 80, 2 and 40, 4 and 20, 5, and 16, and 8 and 10.

So, the factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, and 80.
