Is the greatest common factor of an odd and even number always 1?
No, the GCF of an odd an even number is not always 1. Odd and even numbers can share factors other than 1. For example, the greatest common factor of 5 and 10 is 5.
Why do all numbers other than square numbers have even factors?
All numbers can be broken down into factor pairs. No matter how many pairs there are, it's an even number of factors. Squares have a factor pair that consists of the same number twice. When you list them, you list the number once.
Is the greatest common factor of two numbers is equal to the lesser of the number?
Well, not always. The GCF and LCM of 10 and 10 is 10. But apart from that special circumstance, the statement is true. Apart from a number itself, all of its factors are smaller than it. Apart from a number itself, all of its multiples are larger than it. You can't have a GCF that is greater than the smaller number, and you can't have an LCM that is less than the larger one which means that the LCM of two numbers will never be less than the GCF. Factors go into numbers, numbers go into multiples.
What number less than 13 has the most factors?
1 is the number less than fifty with the fewest number of factors. All other numbers have at least two factors (1, and the integer itself).
Is a factor a multiple?
As a general rule, multiples tend to be larger than factors. This is not always true. 9 is a factor of 27. 6 is a multiple of 3. The important distinction is in the relationship to the number they are factors or multiples of. A factor will be equal to or lesser than the number. A multiple will be equal to or greater than the number.
What number other than one is a factor of all even numbers?
Two is.
What number other than 1 is a factor of all even numbers?
Its 2.
What is they only even prime number?
The answer is two. Any even number has 2 as a factor, since that's the definition of "even". And if an even number is larger than 2, it will have other factors as well.
What is the even number that is greater than 3 and is a factor of 20?
4 is greater than 3 and is a factor of 20.
Is the greatest common factor of two even numbers always even?
Assuming the second even number is equal to 4 or greater, than the highest common factor of the two numbers is equal to an even number 2 or greater. Why can't an odd factor be used? Any odd factor must be multiplied by (at least) 2 to create an even product (ie. the 1st even number). That same odd factor must be multiplied by (at least 2) and any other number to create a 2nd even product, thereby making the Greatest Common Factor (at least) 2 times the odd number....which is an even number.
Is 280 a composite number?
YES. 280 is a composite number because it is even and for sure it has another factor other than 1 and itself which is 2.
What number is less than 20 is a prime number is a factor of 52 and is an odd number?
The number you are looking for is 13. The other factor is 2, but 2 is even, so 13 is the only possibility. 52=13*2*2
Is the greatest common factor of an odd and even number always 1?
No, the GCF of an odd an even number is not always 1. Odd and even numbers can share factors other than 1. For example, the greatest common factor of 5 and 10 is 5.
Can you always find a third factor for larger even numbers?
Yes. An even number will always have as it's factors, itself, 1, 2 and another number. So the minimum number of factors for an even number other than 2 is four.
Is 0 a factor of all numbers?
0 is not a factor of any number other than itself. If N is any number, than there is no other number P such that N = 0 * P and that means that 0 is not a factor of N. The only number that is a factor of all numbers is 1.
Why are all prime numbers other than 2 odd?
Because every other even number has at least a factor of two, preventing it from being prime.
What is the number that has three digits less than 140 has 7 factor its even of the number is less than 9?
what is the number that has three digits less than 140 has7 factor the sum of the digits of the number is less than 9
