Is 567 a prime number or a composite number?
A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 567 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 3. (You can check this by adding the digits of the number: 5 + 6 + 7 = 18. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Therefore, 567 is a composite number.
Is 501 a prime number or a composite number?
A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 501 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 3. (You can check this by adding the digits of the number: 5 + 0 + 1 = 6. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Therefore, 501 is a composite number.
What does it mean for a number to be a common factor of two?
All numbers have factors. Some numbers have some of the same factors as other numbers. These are known as common factors. 3 is a factor of 9. 3 is a factor of 15. 3 is a common factor of 9 and 15.
What is semiprime number?
One with one prime factor and one other factor ...or it might be one with two factors both of which are prime...
What three different whole numbers multiply together to make 465?
Look for factors. Start with small factors, such as 2, 3, 5, 7. Once you find a factor, divide the number by that factor to get the other factor. Continue looking for smaller factors for this smaller factor.
What is an easier way to find the factors of a number?
You can reduce the number by known factors to make it more manageable. Plus there are tricks for different numbers: If the number is even, then 2 is a factor. If the digits add up to a multiple of 3 then 3 is a factor. If the ones digit is a 5 or 0 (with a tens digit greater than or equal to 1), then 5 is a factor. If the ones digit is a 0 then 10 is a factor. If the digits have the property that the first minus the second, plus the third, minus the fourth, (alternating signs) equals 0, then 11 is a factor. There are other tricks but these factors would be the most common.
What are the factors and prime factors of 1789?

What is a square factor?
They are square factors that are factors of other numbers as for example 9 is a square number that is a factor of 27
Why is 12 a composite number?
A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 12 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 3. (You can check this by adding the digits of the number: 1 + 2 =3. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Therefore, 12 is a composite number.
Why 81 have an odd number of factors and 40 have an even number of factors?
A number will have an odd number of factors if and only if one of those factors is the square root of the number. This is because any factor of a number you can find must pair up with another factor of that number, and multiply to give the number. The only exception is when the factor would be paired with itself. In other words, be the square root. 81 is a square number, and so the factor 9 (square root of 81) will not pair with any other factor, meaning 81 will have an odd number of factors. 40 has an even number of factors, because it is not a square number, and so all its factors can pair up.
What group of number are all the whole number factors of a prime number?
There are exactly two whole number factors of any prime number. The first factor is '1'. The other factor is the prime number itself.
Is 231 a prime number or a composite number?
A prime number is a number with two and only two factors: 1 (also known as unity) and itself. A composite number is a number with more than two factors; in other words, it has at least one factor besides 1 and itself. 231 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 3. (You can check this by adding the digits of the number: 2 + 3 + 1 = 6. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Therefore, 231 is a composite number.

What are factor of a number?
The factors of a number are the numbers that can be multiplied together to get the number. 2 x 4 = 8 Two and four are factors of eight.
What is common prime factors?
All numbers have factors. Some numbers have some of the same factors as other numbers. These are common factors. If the factor is a prime number, it is a common prime factor. 3 is a prime number. 3 is a factor of 9. 3 is a factor of 12. 3 is a common prime factor of 9 and 12.
Factor vrs multiples?
Any number is a factor and a multiple of itself. Other factors are less than the number, other multiples are more. 5 is a factor of 10. 10 is a multiple of 5.
