# Do all even numbers have all 2 as a factor Explain?

Yes, all even numbers have two as a factor because that is the definition of an even number.

### Do all even numbers have a factor of 2 explain?

Yes, all even numbers have a factor of two due the fact that the are of an even sequence and can be divisible by two which is also an even number. Any number that is even is not prime because is can be divided by the factor 2, but two itself is a prime number as its only factors are itself and 1. All even number have to have a factor of two e.g 4…

### Is it true or false that two composite numbers are relatively prime and explain?

Two composite numbers may or may not be relatively prime, depending on their factors. Relatively prime numbers are sets of two or more numbers having 1 as their greatest common factor (gcf). All even numbers have 2 as a common factor, so no even number is relatively prime with any other even number.

### Why do all even numbers have 2 as a factor?

All even numbers have 2 as a factor because they are all divisible by 2. Half of the numbers are odd and half of them are even. It makes sense that half of them would be divisible by 2. Because of the definition of an even number (an even number is an integer that can be divided by 2 evenly; with no remainer).

### When multiplying an odd number by an odd number why is the result odd?

The product of multiplication results in a number that has all of the factors of the two numbers being multiplied. All even numbers have the prime factor 2. Since no odd number has the factor 2, no product of those numbers can have it. So: - Odd numbers times odd numbers produce odd numbers. - Odd numbers times even numbers produce even numbers. - Even numbers times even numbers produce even numbers.
