Composite numbers from 1 to 100 are numbers that have more than two factors (1 and themselves).
Understanding Composite Numbers
A composite number is a positive integer that can be formed by multiplying two smaller positive integers. Equivalently, it is a positive integer that has at least one divisor other than 1 and itself. Prime numbers, on the other hand, have exactly two factors: 1 and themselves. The number 1 is neither prime nor composite.
List of Composite Numbers from 1 to 100
Here's a list of all the composite numbers between 1 and 100, derived from the provided reference:
| 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 |
Examples
- 4 is composite because it can be divided by 1, 2, and 4.
- 12 is composite because it can be divided by 1, 2, 3, 4, 6, and 12.
- 25 is composite because it can be divided by 1, 5, and 25.
- 91 is composite because it can be divided by 1, 7, 13, and 91.
Identifying Composite Numbers
Here’s how to identify composite numbers:
- Check if the number is greater than 1.
- See if the number has divisors other than 1 and itself. If it does, it is a composite number.
Conclusion
The list provided comprehensively covers all composite numbers within the range of 1 to 100, fulfilling the request of the prompt.
