Yes it is possible to determine if a product will be even or odd. To do this, we need to consider what an even number is. Even numbers are numbers with at least one factor of 2 (meaning they are divisible by 2). Thus, any product of numbers which contains at least one even number will result in an even product.

If all of the numbers being multiplied together are odd, the product will be odd. If one or more of the numbers is even, the product will be even.

Without knowing what the product is, it will be difficult to help. Presumably, you can tell the difference between even and odd numbers. If you are trying to predict, the product of two evens is even, the product of two odds is odd and the product of an even and an odd is even.

If you are multiplying negative numbers, an odd number of factors will have a negative product. An even number of factors will have a positive product.

Given any number, there is an even number that exists greater than it. That even number is a product: of 2 and some number. Therefore, the number that you started with is less than the product of a pair of numbers.

If the GCF of the two numbers is 1, the LCM will be their product. IF the GCF is greater than one, the LCM will be less than the product.

If there are no prime factors in common, the LCM will be the product of the two numbers. If common factors exist, the LCM will be less. It will never be more.

If you multiply two reciprocals, their product must be 1.

The "mean" of a group of numbers is their "average". It doesn't tell you what the numbers are, or even how many numbers there are.

All even numbers are divisible by 2 with no remainder. Why are the numbers 1.3499,2.4596,4.4817 classed as even numbers? And 1.8221, 3.3201 are classified as odd numbers in numerical integration

Yes, all you have to do is to count the number of ODD numbers in the list. If it is odd, then the sum will be odd; if even, so will the sum. Knowing this can help you run a quick validity check when you sum up a list of numbers. (The method works because: a) the sum of two even numbers is even, and b) the sum pf two odd numbers is even, but c) the sum of an even number and an odd number is odd. Hence, if you only determine whether there are any unpaired odd numbers, you know the answer.)

It's even. All even numbers are divisible by 2.

If the GCF of a given pair of numbers is 1, the LCM will be equal to their product. If the GCF is greater than 1, the LCM will be less than their product. Or, stated another way, if the two numbers have no common prime factors, their LCM will be their product.

There is not one exclusive name for these numbers, but I'll tell you this: PRIME NUMBERS HAVE EVEN NUMBERS OF FACTORS
