They are numbers which are not common multiples.

6 : 7

There are eleven such numbers.Get the common multiple of those numbers. All other common multiples will be multiples of this common multiple; that is, you can multiply the common multiple by 1, by 2, by 3, etc. to get additional numbers that are multiples of both numbers.

1 and 2

Just 72. It was found by multiplying 8 and 9. --------------------------------------- The common multiples of two numbers are the multiples of their lowest common multiple. LCM(8, 9) = 72 The common multiples of 8 and 9 are 72, 144, 216, ... The only common multiples less than 100 are 72 only.

There are 2 such numbers: 35, 70

When their GCF is greater than 1. When they have prime factors in common.

All nonzero numbers have an infinite amount of multiples.

Numbers that are prime can't be multiples of 10. Multiples of 10 can't be odd.

The lowest common factor between two numbers is the multiple apart from 1 that the two numbers share which is the lowest. For example: The numbers 36 and 45. Multiples of 36 are {1,2,3,4,6,9,12,24,36} Multiples of 45 are {1,3,5,9,15,45} It is evident that their shared multiples are 1,3,9. But we exclude 1, therefore 3 is the LCM (or LCF)

44 and 88 are the only common multiples of 4 and 11 that are less than 100

0 and negative multiples of 20.

All numbers have an infinite amount of multiples.

All of the composite numbers less than 100 have factor pairs.

12 and 24 12 and 36 24 and 36

The common multiples of 4 and 11 are 44 and 88.

As numbers get larger, it is more likely that they will be multiples of something.

9,18,27,36,45,54,63,72,81,90,99

63.

109 whole numbers greater than 9 and less than 999 are multiples of 9

4 and 6 6 and 8 Any time the two numbers have a common factor, their LCM will be less than the product because the common factor contributes to the LCM fewer times than it contributes to the product.

3. All other multiples of 3 are not prime.

There are 3 such numbers: 30, 60, 90.

-- Real numbers -- Rational numbers -- Integers -- Negative numbers -- Multiples of 5 -- Multiples of -5 -- Numbers less than -4.9 -- Numbers greater than -5.1

The highest common factor of 6 and 8 is always 2 - it has to be less than or equal to the smaller of the two numbers.If you mean the highest common multiple of 6 and 8 less than 100, then it is 96.All common multiples of 6 and 8 are multiples of their Lowest Common Multiple.The LCM(6, 8) = 24, thus all common multiples of 6 and 8 are multiples of 24.The largest one less than 100 is:100 ÷ 24 = 41/6⇒ highest multiple of 24 less than 100 is 4 x 24 = 96.
