All numbers with a least common multiple, have that multiple as a factor.
Only if they're the same number.
Yes, they are the same thing.
The same as the product of 84 and 90.
It has to be at least two. The GCF and LCM of 10 and 10 is 10.
The GCF and LCM of 10 and 10 is 10.
no GCF (Greatest common factor) is different from LCM (least common multiple)
The LCM of 15 and 25 is 75. The least common multiple of two numbers is the product of the two numbers divided by their greatest common factor. The greatest common factor of 15 and 25 is 5. (See related question "What is the greatest common factor of 15 and 25?" for this calculation.) So, the least common multiple is 15 x 25 ÷ 5 = 75. The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.
Only if the magnitudes of two numbers are the same.
The least common multiple of 3, 4, 5, and 9 is 180. The least common multiple (LCM) is often also called the lowest common multiple or smallest common multiple. Keep in mind that these different terms all refer to the same thing: the smallest positive integer which is a multiple of two or more numbers.
6 is the greatest common factor. 1 is always the least common factor, I am pretty sure you mean the GCF, not the LCF. Look at factors of 18. 18 itself is not a factor of 24, neither is 9 the next factor, but 6 is a factor of both. Nobody really cares about Least common factors, since it is always the same. There is least common multiple? In case you want the LCM, the least common multiple of two numbers is the product divided by the GCF, so is 18 * 24 / 6 = 72
