### Is the product of 2 prime numbers always even?

No, the product of 2 prime numbers is not always even. If one of the prime numbers is 2, then the product will be even. However, if both prime numbers are odd, then the product will be odd.

### The product of odd numbers is always even?

An even number can be divided by 2 evenly. An odd number will have a remainder of 1 when divided by 2. Odd times odd is always odd.

### Is the product of any two prime numbers is always odd?

No, because 2 is prime. Otherwise the product of two odds is odd, and all primes are odd except 2.

### What is the result of product of even numbers and odd numbers?

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.

### What do you know about the product of odd and even numbers?

There are 3 cases: An even number time an even number such as 2*6=12 is always even. Proof: Since even numbers can be expressed as 2*X and 2*Y, their product is 4xy which is even. An even number times an odd number (same as odd times even) such as 2*3=6 is always even. Proof: 2X represents an even number and 2Y+1 represents an odd number. Their product is 4XY+2X=2(2XY+X), which is even. An odd number times an odd number such as 11*11=121 is always odd. Proof: Let 2X+1 and 2Y+1 be the two odd numbers. Their product is 4XY+2X+2Y+1 = 2(2XY+X+Y)+1, which is odd. Summary: the product of two numbers is always even unless the two numbers are both odd.

### What is a conjecture about the product of 2 odd numbers?

Their product will also be an odd number.

### Is the product of 2 numbers always going to be odd?

no. 16 + 2 = 18 right? and 2 + 2 = 4 so no.

### Is the product for any two prime numbers always odd?

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.

### Is it true that the product of any two prime numbers are always odd?

Not always because as for example 2*19 = 38

### Can product of 2 odd no be even?

The product of two odd numbers is never even.

### What is a conjecture for multiplying two odd numbers?

One possible conjecture: The product is always an odd number. Another possible conjecture: The product is always greater than either of them. Another possible conjecture: Both odd numbers are always factors of the product. Another possible conjecture: The product is never a multiple of ' 2 '. Another possible conjecture: The product is always a real, rational number. Another possible conjecture: The product is always an integer.

### Is the product of two odd number always odd?

NO. The product of any two prime numbers are not always odd.Examples:2 x 3 = 62 x 5 = 102 x 11 = 22
