No. A multiple cannot be less than the number it is compared to. An LCM can never be less than the greatest number in the set.

No.

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

It's never less than the largest number.

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.

Because the LCM has to be a multiple of both numbers. A number can't have a multiple smaller than itself.

Yes, GCF means Greatest Common Factor For example the GCF of 15 and 18 is 3 which is less than both 15 and 18.

10 and 49

The GCF of 2 numbers can be less than either number.

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.

That's true whenever both of the original numbers are less than ' 1 ' ... only decimals, with no whole number before the point.

The total number of prime numbers less than 100 is 25.

I think so. -4 and -5 are both rational numbers. Their sum is -9, which is less than both of them individually.

How many numbers less than 700 are divisible by both 15 and 21?

There are 10 numbers less than 101 which have an odd number of factors: 1,4,9,16,25,36,49,64,81,100.

No. The LCM of 9 and 4 is 36.
