How can you tell whether the product of a multiplication problem will be odd or even?
You can tell it will be even when the number you are multiplying has a 2 4 6 8. You can tell it will be odd when the number you are multiplying has a 1 3 5 7.
Can you tell a prime or composite number by seeing if its odd or even?
You cannot. If a number is even - other than 2 - then it is a composite number. However, if it is odd, it is not easily possible to tell whether it is prime or composite.
How can you tell wether a number is even or odd?
To determine if a number is even or odd, you can check if the number is divisible by 2. If the number is divisible by 2 without leaving a remainder, then it is even. If the number is not divisible by 2 or leaves a remainder when divided by 2, then it is odd.
Test whether a number is even or odd?
An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2.
How can you use the prime factorization of a number to determine whether the number is even or odd?
If the factorization includes the number 2, it's even. If not, it's odd.
