3 is a common factor but not the Greatest common factor.
3 isn't the GCF. It would be 30(2 + 3)
As a general principle, you can find the LCM of two numbers by dividing their product by their GCF. This one won't work. The product of any two numbers with 5 as a common factor would have to end in 5 or 0.
The general rule is that the product of the LCM and the GCF is equal to the product of the original two numbers. That would make the answer 20. Lets overlook the fact that two numbers with a GCF of 15 and an LCM of 20 don't exist.
It depends on what the numbers are. For example, if the prime numbers you were talking about were 3 and 7, the least common multiple would be 21. If your numbers were 2 and 3, it would be 6.
2 x 2 x 3 = 12
The prime factors of a number by multiplying each other. You can also use exponents. a prime factorization is when you divide a number and see what all of the prime (odd) numbers make up that number. EX. 9 / \ 3 3 then you would circle the 3's because they are prime.
The girl was such a perfectionist, if she made a mistake she would rather rewrite the whole page than use an eraser. Being a perfectionist is mentally and emotionally tiring.
If the sum of 2 numbers is 25 and their product is 156, the 2 numbers would be 12 and 13.
A number as a product of prime numbers would be "x".
The product of two numbers is the resulting number when they are multiplied together. As there is an infinite amount of numbers it would be impossible to write out the result of the product of all pairs of numbers
The LCM of two numbers is their product if and only if the two numbers are co prime, that is their HCF is 1. Otherwise their LCM in not their product, in fact, it is their product divided by their HCF.
No whole number would fit (their product would be even for starters).
If all three numbers are positive then the product obviously has to be positive. If TWO of the three numbers are negative, then the product is also positive. But if exactly ONE of the three numbers is negative or if all THREE are negative, then the product must be negative. In general, a product of numbers is negative if an ODD NUMBER of the terms is negative.
I would describe the rule as one of the simplest possible.The product is odd only if each of the natural numbers is odd. If any one of them is even, the product is even.I would describe the rule as one of the simplest possible.The product is odd only if each of the natural numbers is odd.

Yes. What else would it be?
These numbers have to be multiplied/added by other numbers in order to get other numbers. Otherwise I assume you mean the sum of 2+0 which is 2, and the product of 9x1 which would be 9.
