The LCM is never less than the greatest number in the set. The LCM of 4 and 9 is 36.
both number are less than 10, the distance between the two number on the number line is 14
The LCM for any pair of natural numbers can be as big as their product.
Only one number can be both even and prime, and that is the number 2.
No. The LCM of 4 and 6 is 12.
That would depend on how many numbers are on the spinner and the cube. The more numbers there are, the less likely it is that they would both land an any given number.
Yes, GCF means Greatest Common Factor For example the GCF of 15 and 18 is 3 which is less than both 15 and 18.
No. A rational number is ANY number that can be represented as one integer over a second integer (which cannot be zero). There is no requirement that the top integer is less than the bottom integer (an improper fraction is still a rational number - all integers are rational numbers as they can be represented as an improper fraction with a 1 as the denominator). Only if both rational numbers are less than 1 will the result of multiplying them together be less than both of them. If one rational number is greater than 1 and the other less than 1, then the result of multiplying them together is greater than the number less than 1 and less than the number greater than 1. If both rational numbers are greater than 1, then the result of multiplying them together is greater than both of them.
