To find the prime number between 3 and 15, and also a factor of 20, we can follow these steps:
Step 1: Identify prime numbers between 3 and 15
Prime numbers are numbers that are only divisible by 1 and themselves. The prime numbers between 3 and 15 are: 3, 5, 7, 11, and 13.
Step 2: Check if each prime number is a factor of 20
To determine if a number is a factor of another number, we divide the second number by the first number and check for a remainder of 0.
Let's check each prime number between 3 and 15:
3 is a factor of 20 because 20 divided by 3 gives a remainder of 2.
5 is a factor of 20 because 20 divided by 5 gives a remainder of 0.
7 is not a factor of 20 because 20 divided by 7 gives a remainder of 6.
11 is not a factor of 20 because 20 divided by 11 gives a remainder of 9.
13 is not a factor of 20 because 20 divided by 13 gives a remainder of 7.
Step 3: Conclusion
Based on the above calculations, the prime number between 3 and 15 that is also a factor of 20 is 5.
