61 x 1 = 61.
Their product will also be an odd number.
Yes.
The product of two odd numbers is never even.
yes
It is: 2 and 61
61 and 71 or 65 and 67.
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 multiplication results in a number that has all of the factors of the two numbers being multiplied. All even numbers have the prime factor 2. Since no odd number has the factor 2, no product of those numbers can have it. So: - Odd numbers times odd numbers produce odd numbers. - Odd numbers times even numbers produce even numbers. - Even numbers times even numbers produce even numbers.
even
No, because 2 is prime. Otherwise the product of two odds is odd, and all primes are odd except 2.
More than possible. Unless one of your prime numbers is 2, the product of any other two will be odd.
