Yes, two natural numbers always have a least common multiple.
Yes, if it is a multiple of the smaller number.
Common multiple. Incidentally, it need not be the least common multiple. Using the least common multiple instead of any common multiple means that the numbers involved in the calculations are smaller but does not mathematically alter the results.
No, it's a common factor. Multiples can't be smaller than the numbers.
If one number is divisible by another (in this case, 15 is divisible by 5), then the least common multiple is equal to the larger of the numbers (15), and the greatest common factor is equal to the smaller of the numbers (5).If one number is divisible by another (in this case, 15 is divisible by 5), then the least common multiple is equal to the larger of the numbers (15), and the greatest common factor is equal to the smaller of the numbers (5).If one number is divisible by another (in this case, 15 is divisible by 5), then the least common multiple is equal to the larger of the numbers (15), and the greatest common factor is equal to the smaller of the numbers (5).If one number is divisible by another (in this case, 15 is divisible by 5), then the least common multiple is equal to the larger of the numbers (15), and the greatest common factor is equal to the smaller of the numbers (5).
There isn't a GCM (greatest common multiple) because multiples have an unlimited supply; numbers have no end. For example, the number 10,000,000,000,000 is smaller than 10,000,000,000,000,000,000,000.
The GCF of the numbers is the greatest common factor no matter what their relationship is. When one number is a multiple of another number, the GCF is the smaller number.
When one number is a multiple of the other, the greatest common factor of the two is the smaller number.
No. As a general rule, multiples cannot be smaller than the numbers they are compared to.
A common multiple is a number that two or more other numbers can both go into. For example, a common multiple of 2, 4, and 6 would be 12.Not sure what you mean by a "comman" multiple, but a commonmultiple of a set of numbers is a number that is a multiple of each number in the set. That is, it is in the multiplication table of each of the numbers in the set. Note, though, that for this purpose, the multiplication tables do not stop at 10 times or 12 times.All numbers have multiples. Some numbers have some of the same multiples as other numbers. These are known as common multiples.18 is a multiple of 6.18 is a multiple of 9.18 is a common multiple of 6 and 9.All numbers have multiples. Some numbers have the same multiples as other numbers. These are called "common multiples."12 is a multiple of 3.12 is a multiple of 4.12 is a common multiple of 3 and 4.
It depends on whether "20 natural numbers" means any 20 natural numbers, or 20 different natural numbers. If the 20 numbers must all be different, the best I've been able to come up with is: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 72, 90, 360. The least common multiple of these twenty numbers is 360. If numbers can be duplicated: 3 (once) and 42 (19 times) Least common multiple is 42.
Lowest common multiple is the smallest whole number that is divisible by all the numbers. eg. the lowest common multiple of 70 and 14 is 14, the lowest common multiple of 2 and 3 is 6, or 7 and 8 is 56 etc. Normally found by multiplying the two numbers together, then seeing if there are any smaller than that
