The first odd Prime number is 3. 3 x 3 x 3 x 3 = 81
What else can I help you with?
Is 4 a multiple of 78?
No, it is a factor. Multiples are always greater than the number itself, factors are smaller.
Can an even number greater than 3 be prime?
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.
Are all multiples of 2 greater then 2 are composite numbers explain?
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.
Is 28 a prime explain how?
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.
Is it true that the only factor greater than half is itself?
Yes.
Can the greatest commoñ factor of 18 and 36 be greater than 18 Explain?
No. No number can have a factor larger than itself.
Is 4 a multiple of 78?
No, it is a factor. Multiples are always greater than the number itself, factors are smaller.
What is the least number that has four odd factors that are all the same each factor is greater than 1 and can only have 1 and itself as factors explain how you found the number?
The smallest odd prime number greater than one is 3. 3 x 3 x 3 x 3 = 81
What are for the factors that are all the same each factor is greater than 1 and can have only 1 and itself as factors?
The question is garbled but I suspect that the answer is "a prime number".
Whole number greater than 1 whose only factor is itself and 1?
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.
Can the greatest common factor of 18 and 36 be greater then 18explain?
No. No number can have a factor greater than itself.
What is the 9000 greater factor?
Any number is the greatest factor of itself.
Are All factors of twelve are factors of six?
Nope... 12 is a factor of itself - but not a factor of six.
What is the greater factor of 146?
The greatest factor of any positive number is the number itself.
Two prime numbers greater than 2 have 2 as a common factor?
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.
Can an even number greater than 3 be prime?
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.
Is there a prime factor greater than the square root of an integer?
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.
