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)
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.
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).
even
If you multiply one even number by one odd number, the result is always even. In general, if you multiply several numbers, and at least one of the numbers is even, the product is always even. This is because "even" means "multiple of 2", and if one of the factors contains a 2 as a factor, so will the product.
No. the factors may be both even but only one of them needs to be.
No. Since 2 is a prime and any number multiplied by an even is even, the product of all primes must be even.

Both 3 and 5 are prime numbers. 3 x 5 = 15
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.
The product of two odd numbers is never even.
even
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.
The first three even numbers are 2, 4, and 6. To find the product of these numbers, you simply multiply them together: 2 x 4 x 6 = 48. Therefore, the product of the first three even numbers is 48.
Must be the 2 odd numbers, 9 & 15 (P = 135, S = 24)
as 132 is an even number at least one of the two numbers must also be even 12 + 11 = 23 12 x 11 = 132
YES. The product of any two consecutive numbers is even because their product is always a multiple of 2.Examples:2 * 3 = 63 * 4 = 12
