10 and 20
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.
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.
The LCM of two consecutive numbers is their product. The LCM of two consecutive multiples of 5 is their product divided by 5. Two consecutive numbers cannot be multiples of 5.
All nonzero numbers have an infinite amount of multiples.
6 and 12
they are all multiples of two and they are less than 100
You have to have two different numbers to find common multiples
Two common multiples of 21 and 15 are 105 and 315.
The two common multiples of three and five are: 15 and 30 ^-^
Those are known as "common multiples". The smallest POSITIVE of these common multiples is called the "least common multiple".
They are the common multiples of the two numbers.
60 and 120 are the two lowest common multiples.
