The two-digit number 81 is divisible by 9.
To identify the lowest composite number that is a factor of 28, we need to find the factors of 28 and then determine which of those factors is the lowest composite number.
Step 1: Find the factors of 28.
A factor of a number is a whole number that divides evenly into that number without leaving a remainder. Let's find the factors of 28:
The factors of 28 are: 1, 2, 4, 7, 14, and 28.
Step 2: Identify the lowest composite number among the factors of 28.
A composite number is a number that has more than two factors. In this case, we need to find the lowest composite number among the factors of 28, excluding 1 and 28.
The factors of 28, excluding 1 and 28, are 2, 4, 7, and 14.
Now, we need to identify the lowest composite number among these factors. The lowest composite number is 4.
Therefore, the lowest composite number that is a factor of 28 is 4.
So, the answer is:
4 is the lowest composite number that is a factor of 28.
