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.
No. Since 2 is a prime and any number multiplied by an even is even, the product of all primes must be even.
as 132 is an even number at least one of the two numbers must also be even 12 + 11 = 23 12 x 11 = 132
2 x 37 = 74 As the product is an even number one of the prime numbers must be 2. Then just check all the even numbers between 70 and 80 that is double a prime number: 74 = 2 x 37.
As 9506 is even, at least one of its factors must be even - there are no two odd numbers (only) that will multiply together to get 9506. The factor pairs of 9506 are: 1 x 9506 2 x 4753 7 x 1358 14 x 679 49 x 194 97 x 98 97 and 98 are two consecutive numbers whose product is 9506.
All of the factors of 12 are 1,2,3,4,6,12. Therefore, the even factors must be 2,4,6,12.
None. The sum or product of any two even numbers must be even.
At least one of the two numbers has to be even, but both can be even.
no eg: 9x4=36
Yes because the product of each pair of negative numbers must be positive.
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).
No. Since 2 is a prime and any number multiplied by an even is even, the product of all primes 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.
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.
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.

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.
This is not always true. If the sum of two numbers is even, then those two numbers are either both even or both odd. For example: 2 + 2 = 4 (even + even = even) 5 + 7 = 12 (odd + odd = even) 3 + 2 = 5 (odd + even = odd)
