No. Since 2 is a prime and any number multiplied by an even is even, the product of all primes must be 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.

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

The product of two odd numbers is never even.

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 numbers are 28 and 30.

-98

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.

No. 9 X 2 = 18 One is even and one is odd.

The GCF of consecutive even numbers is 2. The LCM of consecutive even numbers is their product divided by 2.

34 & 36

A number that is a multiple of 4.

no.

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

Even numbers must have 2 amongst their factors; they may have other even numbers amongst their factors. Odd numbers must not; every factor of an odd number must be odd.

No. Counter Example: -2 * -2 = 4

No. the factors may be both even but only one of them needs to be.

Must be the 2 odd numbers, 9 & 15 (P = 135, S = 24)

The numbers are 4 and 6.

as 132 is an even number at least one of the two numbers must also be even 12 + 11 = 23 12 x 11 = 132

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.

It is not always even. * * * * * Yes. Since the numbers are even, 2 must be a common factor and so the GCF is a multiple of 2.

The numbers are 6 and 8.

No. Just try it out with 2, or 4, negative numbers.
