The number which has only those factors is 12.
The factors of 4 are 1, 2, and 4. The only prime factor of 4 is 2. The factors of 20 are 1, 2, 4, 5, 10, and 20. The prime factors of 20 are 2x2x5.
no 4 is not a prime number because the factors are 1 and 2 and 4. Not 1 and 4 only
The factors of a prime number are 1 and the number itself. 3 is a prime number, so its only factors are 1 and 3. Factors of 4 are 1 2 4, so 1 is the GCF of 3 and 4 because it is the only factor common to both numbers.
If factors include 1 and the number itself then the any number (n) with only 4 factors has to be the product of two prime numbers, p1 and p2. The factors are then n, p1, p2, and 1. The largest 3-digit number with only 4 factors is 998. The factors are 998, 499, 2 and 1
Three is prime, because the number 3 only has 2 factors 1 and itself and the number 4 has 3 factors 1,2, and 4 (you can tell if a number is prime when it has 2 factors and if a number has more than 2 it is composite)
factors are a number that will go into a number for example 2 is a factor of 4 becuse 2 goes into 4 evenly if a number only has two factors 1 and itself it is considered prime... hope that helps :)
There are only three positive integer factors of 4. Perhaps you meant multiples, of which there are an infinite number.
The only proper factor of four is two.
Answer: The factors of the number '4' are 1, 2, and 4.
Zero is not a factor of 4. Zero is only a factor of zero! The factors of 4 are 1, 4, 2 The factors of zero are zero and any other number. Therefore the common factors are 1,2 and 4
A prime number is a number that is divisible only by 1 and itself. It has no other factors. The factors of 3 are 1 and 3. It can be factored only as 1 x 3. The factors of 4 are 1, 2, and 4. It can be factored as either 1 x 4 or 2 x 2. The factors of 10 are 1, 2, 5, and 10. it can be factored as either 1 x 10 or 2 x 5. Therefore, 3 is the prime number.
