Is 147 a prime or composite number?

Answer 1

147 is a composite number. Its factors are 1, 3, 7, 21, 49, and 147.
Note that the sum of the digits of 147 is 12. If the sum of the digits of any number is a multiple of 3, then the number has 3 as a factor. So sine 12=4x3, we know that 147 is divisible by 3 and that makes it composite.

Answer 2

147 has factors other than 1 and itself, so it is not a prime number. For example, 147 is divisible by 3. (You can quickly check this by adding up the digits of 147: 1 + 4 + 7 = 12. If the sum of the digits is divisible by 3, so is the number.) Therefore, 147 is a composite number.

Answer 3
