Hi
False 12 and 9. The lowest is 3. Odd number
2 and 13
"IT IS ALWAYS A ODD"
No. Sum of odd + odd = even Sum of odd + even = odd Sum of even + even = even
For 'odd' prime numbers this is true, but '2' is also a prime number , so you will have an even answer. Remember when multiplying even X even = even even X odd = even odd X even = even odd x odd = odd.
This would be easier with the other number. The LCM of 4 and any odd number is their product. The LCM of 4 and any even number is either the other number or half the other number depending on whether it is a multiple of 4 or not.

LCM stands for "least common multiple." By definition, they are multiples of each number, odd or even.
Of course they can: 2, 3 & 5: LCM 30
Because the second number from an odd number is odd, and every other number is an odd number. In fact, if you add or subtract an even number with any number, the result keeps the same parity as the other number. So an odd number minus an even number is odd, while an even number minus and even number is even.
The LCM of 2 and any odd number is their product.
If the missing number is even, it's the LCM. If it's odd, it's half of the LCM.

That happens because 5 is an odd number. An odd number times an odd number will give you an odd product; an odd number times an even number will give you an even product. The same happens for the multiples of any other odd number.
Yes. One has to be the square of an odd number. The other square has to the the square of the even number either before or after the odd number. If this is confusing just plug in real values. In either case, an odd times and odd is odd. Therefore one of the squares has to be odd. AN even times an even, however, is always even. Therefore, the second square has to be even. Thus, one of the squares is even and the other is odd. An even plus and odd is always odd.
odd * odd = odd answer even * even = even answer odd * even = even answer
