Do all numbers have 4 factors?
Every number that is a square of a prime p has exactly three factors: 1, p, and p2. Numbers of the form p3 for some prime p, or of the form p x q, where p and q are distinct primes, have exactly four factors. (You might consider 1 in each of the sets as p0 and q0, respectively). For example, 72 = 23 x 32.
What are the pair factors of 4?
The positive pair factors of 4 are (1, 4) and (2, 2).
How do you know if a number is a factor of 4?
Divisibility Rules If a number ends with a 0 or a 5, it’s divisible by 5, i.e. 5 is a factor. If a number is divisible twice by 2, it’s divisible by 4, i.e. 4 is a factor.
How do you find the factors of 4?
4 = 1 x 4 or 2 x 2. Factors of 4: 1, 2, 4. Prime factorization: 4 = 2 x 2, which can also be written 4 = 2². Since √4 = 2, a whole number, 4 is a perfect square.
Which number has more than 4 factors?
| Number | Composite, Prime, or Neither? | Explanation |
|---|---|---|
| 3 | Prime | 3 has only the factors 3 and 1. |
| 4 | Composite | 4 has more than two factors: 1, 2, and 4, so it is composite. |
| 5, 7,11,13 | Prime | Each number has only two factors: 1 and itself. |
| 6, 8, 9,10, 50, 63 | Composite | Each number has more than two factors. |
What is the highest unit number that has four factors?
Number 6 is the greatest single digit number having 4 factors.
What is a multiple of 4?
Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, …
How do you know if a number has four factors?
For a number to be have four factors, it must satisfy the following conditions:- If number is a product of exactly two prime numbers (say p, q). Thus we can assure that it will have four factors i.e, 1, p, q, n. If a number is cube of a prime number (or cube root of the number is prime).
How many prime numbers have exactly 4 factors?
So, any number which is a product of 2 distinct prime numbers has exactly 4 factors. Every number (except 1) has a minimum of 2 factors i.e 1 and the number itself. This means that we are looking for a number x that can be written as,
What are the four factors of a cube of 8?
Thus we can assure that it will have four factors i.e, 1, p, q, n. If a number is cube of a prime number (or cube root of the number is prime). For example, let’s say n = 8, cube root = 2 that means ‘8’ can be written as 2*2*2 hence four factors are:- 1, 2, 4 and 8.
How many types of formulas are there for factors?
There are basically three types of formulas considered for factors. They are: Let us assume N is a natural number, for which we need to find the factors. If we convert N into the product of prime numbers by prime factorization method, we can represent it as; where X, Y and Z are the prime numbers and a, b and c are their respective powers.
