**How many prime numbers are there in the canonical form 1001?**

7, 11, 13. When we count the number of prime numbers above, we find that 1001 has a total of 3 Prime Factors.

**Is 90 a prime composite or neither number?**

Yes, since 90 has more than two factors i.e. 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90. In other words, 90 is a composite number because 90 has more than 2 factors.

### What are the composite numbers from 1 to 1000?

4, 6, 8, 9, 10, 12, 14, 15, 16, 18, 20, 21, 22, 24, 25, 26, 27, 28, 30, 32, 33, 34, 35, 36, 38, 39, 40, 42, 44, 45, 46, 48, 49, 50, 51, 52, 54, 55, 56, 57, 58, 60, 62, 63, 64, 65, 66, 68, 69, 70, 72, 74, 75, 76, 77, 78, 80, 81, 82, 84, 85, 86, 87, 88, 90, 91, 92, 93, 94, 95, 96, 98, 99, 100.

**Is 91 a prime no?**

Prime numbers are the numbers which have only two factors, the number itself and 1. 91 has more than 2 factors i.e 1, 7,13, and 91 so 91 is not a prime number.

**Is 143 a prime no?**

No, 143 is not a prime number. The number 143 is divisible by 1, 11, 13, 143. For a number to be classified as a prime number, it should have exactly two factors. Since 143 has more than two factors, i.e. 1, 11, 13, 143, it is not a prime number.

## What is the sum of prime factors of 1001?
