45, 90, 135
70, 140, 210
They are the first three multiples of LCM(5, 9), that is, the first three multiples of 45.
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
That's not going to work. Multiples of 5 end in 5 or 0. With three numbers, one of those would have to repeat.
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
for three 3 6 9 12 for five 5 10 15 20 these both numbers dont share a common denominator in the first 4 multiples
Since you didn't specify a single number, and all numbers are multiples of themselves, the five smallest multiples are the counting numbers 1 to 5.
write the first three common. multiples of 3,4,5
5: 5, 10, 15 9: 9, 18, 27 If you are looking for the lowest common multiple between 5 and 9 it would be 45. By the way multiples are just counting by the number itself. e.g. 5, 10, 15, 20, 25, 30, 35 (just count by fives or if the number was anything else count by that number)
There are 720 of them.
There are more than 5 multiples of three, but here are the first 5: * 6 * 9 * 12 * 15 * 18
5,10,15 6,12,18the above is true if you wanted the multiples of the numbers separately. If you were looking for the three first COMMON multiples of the numbers, they are...30, 60, 90.The first (or least common) multiple of two numbers is also equal to the product of the two numbers divided by the greatest common factor of the numbers. Since 5 is prime, and 6 is NOT a multiple of 5, then the greatest common factor is 1. Thus, the least common multiple is 30.To find the second multiple, take the first times 2, for the third, take the first times 3, etc......
