because it is going up and multiplacation
is the shortcut of addition.
Yes, two natural numbers always have a least common multiple.
Yes, the least common multiple of two numbers is always divisible by those numbers' greatest common factor.
No, only if the numbers are relatively prime.
A number is an exact multiple of each of a group of numbers. For example, 15 and 30 are common multiple of 3 and 5.
yes
Yes - if two numbers share no common factors (besides 1) the least common multiple will be the product of the numbers.
It is infinite but the lowest common multiple is 4500
The product of all pairs of prime numbers is always the least common multiple of the two prime numbers.
Yes. If A and B are any two whole numbers then A*B is a common multiple. Then either A*B is the least common multiple of A and B or one of its factors is.
No, this will find a common multiple, but not always the least. For example, 2 and 4 have a least common multiple of 4 but if you multiply them you get 8. In fact, the LCM will only be the product of two numbers if the numbers have no common factors. We call numbers with no common factors relatively prime.
Sometimes, not always.
Yes.
