The first two common multiples of the pair of numbers 4 and 6 are: 12, 24.
Since 3 and 5 are both prime numbers, the only common factor of the two numbers is 1. Perhaps you are thinking of common multiples, the first two common multiples of the two numbers are 15 and 30.
The common multiples of any two (or more) numbers are multiples of their lowest common multiple (lcm). lcm(9, 11) = 99 → first five common multiples are: 99, 198, 297, 396, 495
The common multiples of an set of numbers are the multiples of their lowest common multiple. lcm(7, 8, 9) = 504 → the first 3 common multiples of 7, 8, 9 are 504, 1008, 1512.
Add the first to itself.
Multiples of 983 include 983, 1966, 2949 and 3932. For them to be common, they need to be compared to another set of multiples.
A single number cannot have common multiples, until you are comparing it with one or more other numbers.
All the common multiples of a set of numbers are the multiples of their lowest common multiple: lcm(5, 8, 10) = 40 → first three common multiples are 40, 80, 120
You can't have common multiples if they have nothing to be in common with however the first 3 multiples of 9 are 9,18 and 27 Think of just your times tables when finding out Multiples to find the first 5 multiples just count by 9's until you have said 5 numbers and Bingo
To find common multiples of numbers, you would first identify their prime factors. However, in this case it is clear that there are no prime factors, as we have two prime numbers (3 and 5) and one number made up of uncommon prime factors (4 which is 2x2). So instead, the lowest common multiple will just be these three numbers multiplied together. 3x4x5=60. To find other common multiples of 3,4 and 5 we simply multiply 60 by an integer, such as 60x2, 60x3, 60x4, and so on. Thus the first few common multiples of 3, 4 and 5 are 60, 120, 180, 240, and 300
