The first odd Prime number is 3. 3 x 3 x 3 x 3 = 81
No, it is a factor. Multiples are always greater than the number itself, factors are smaller.
No, a prime number has as its only two factors: one and itself. The number 2 satisfies this, but even numbers greater than three would have factors of one and itself, and also have 2 as a factor (because it's even) so then it's not prime.
No since it is an even number it has 2 as a factor. If the factors are the number itself and 1 it is prime. If there are more factors it is not. 28 has many more factors.28=22 x7So 2 and 4 and 7 are all factors as is 14.
Yes.
Yes, all multiples of 2 that are greater than 2 are composite numbers. In addition to 1 and the number itself, 2 is a factor of all even numbers.
No. No number can have a factor larger than itself.
No, it is a factor. Multiples are always greater than the number itself, factors are smaller.
The question is garbled but I suspect that the answer is "a prime number".
The smallest odd prime number greater than one is 3. 3 x 3 x 3 x 3 = 81
A whole number greater than 1 whose only factors is itself and 1 is called a prime factor. 2, 3, 5, 7, and 11, are just a few of them.
Any number is the greatest factor of itself.
No. No number can have a factor greater than itself.
Nope... 12 is a factor of itself - but not a factor of six.
The greatest factor of any positive number is the number itself.
No, a prime number has as its only two factors: one and itself. The number 2 satisfies this, but even numbers greater than three would have factors of one and itself, and also have 2 as a factor (because it's even) so then it's not prime.
No prime number greater than 2 has 2 as a factor. A prime number has only two factors, 1 and the number itself. All prime numbers have 1 as a common factor. Numbers with any number besides 1 as common factors are composite numbers.
No there is not. If you are looking for prime factors of a number and you get to the square root of that number you can stop. Yes, there is. If an integer is not itself a prime, then one of its factors will be less or equal to its square root and the "co-factor" will be greater than or equal to the square root. But both cannot be greater than the square root so, when searching for factors, you can stop when you reach the square root.
