What two numbers have 8 as factors?
To find the factors of 8 in pairs, multiply the two numbers in a pair to get the resultant number as 8.
- Since 1 × 8 = 8, (1, 8) is a pair factor of 8.
- 2 × 4 = 8, thus, (2, 4) is a pair factor of 8.
- Therefore, (8, 1) and (2, 4) are the factors of 8 in pairs.
What kind of number has only 2 factors 1 and itself?

What is that number whose factors are only 1 and itself?
A prime number is a counting number greater than 1 whose only factors are 1 and itself. A composite number is a counting number that is not prime.
What multiple of 8 is also a factor of 8?
Thus, as per the definition given above, the multiple of 8 is obtained by multiplying some integer with 8. For example, 48, 56, 64 and 96 are all multiples of 8 for the following reasons….8, 16, 24, 32,….., 72, 80, 88,….
8 × 6 = 48 | 8 multiplied by 6 to get 48 |
---|---|
8 × 12 = 96 | 8 multiplied by 12 to get 96 |
What is the smallest number with 8 factors?
24
Therefore, smallest number that has exactly 8 factors = 24.
What is the common factor of 2 and 8?
There are 2 common factors of 2 and 8, that are 1 and 2. Therefore, the greatest common factor of 2 and 8 is 2.
What number has only 2 factors?
prime number
A prime number is a number with exactly two factors. A prime number is only divisible by 1 and itself. Another way to think of prime numbers is that they are only ever found as answers in their own times tables. 11 is a prime number because the only factors of 11 are 1 and 11 ( 1 × 11 = 11 ).
Is 8 prime or composite?
