If the product of two numbers is even does that mean the two numbers must be even?

No. It only means they weren't both odd (or another way, that at least one of them was even). An example would be 8 x 9 = 72; the product is even, yet one of the numbers was odd.

What two even numbers total a odd product?
None. The sum or product of any two even numbers must be even.
What negative numbers add together to get negative 18 and multiply to get negative 63?
81
Why when every three consecutive number are being multiplied it gives you an answer which is an even number?
Any two consecutive numbers must comprise one odd and one even number, so their product must be even. Any three consecutive numbers must include two consecutive numbers so the result still applies.
What numbers must you add to make an even number?
You must add either two odd numbers or two even numbers.
Which pair of numbers has an odd product and an even sum 6 9 12 15?
Must be the 2 odd numbers, 9 & 15 (P = 135, S = 24)
What two even numbers total a odd product?
None. The sum or product of any two even numbers must be even.
If the product of two numbers is even then the two numbers must be even?
At least one of the two numbers has to be even, but both can be even.
If the product of two numbers is even then the two numbers must be even.?
no eg: 9x4=36
If the product of two numbers is even then the two numbers must be even right?
Not necessarily, but at least ''one'' of them must be even, unless the two numbers are both the (irrational) square root of the same even number.
Is the product of an even number of negative numbers positive?
Yes because the product of each pair of negative numbers must be positive.
If the product of two numbers are even then the two numbers must both be even?
No. If you have an odd number (for example 5) and an even number (say 2) and you multiply them together, you will get an even number (10). Therefore, just because the product of two numbers are even does not make both the numbers being multiplied together even (although at least one must be).
Is the product of all prime numbers odd?
No. Since 2 is a prime and any number multiplied by an even is even, the product of all primes must be even.
Why are some odd numbers composite?
Some. Any product of a set of odd numbers will be odd. To be even, a composite number must have at least one even factor. Therefore odd composite numbers must exist.
Why is the product of two even numbers even?
An even number is any number that has '2' as a factor.When you multiply two numbers, you multiply all the factors of both of them.If '2' was a factor of either number, or of both, then it's a factor of their product,and the product must therefore be an even number.
Why is it not possible to make a mean of 7 with 3 even numbers?
because in a mean for 7 with three numbers the total of the 3 numbers must be 21 and (even number) + (even number) = (even number) 21 is odd Q.E.D
What negative numbers add together to get negative 18 and multiply to get negative 63?
