### What Are The Prime Multiples Of 8?

The first five multiples of 8 are 8, 16, 24, 32, and 40.

### What Number Has Only 8 Factors?

Therefore, smallest number that has exactly 8 factors = 24.

### What Are The First 8 Prime Numbers?

So, from the table it is clear that 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97 are the prime numbers.

### What Is Meant By Prime Factorization?

Prime factorization is the process of finding the factors of a certain number by simplifying it with the help of the smallest numbers it is divisible with. This must be done until the end product is 1. For example, if we wish to calculate the factors of 6 using the method of prime factorization, Then 6 ÷ 2= 33 ÷ 3= 1Or one can write 1 × 2 × 3 = 6Thus, the required factors of the number 6 are 6 (as a number is always divisible by itself), 2, 3 and 1.
