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
There are three numbers between 10 and 50 which are divisible by both 3 and 5. All numbers that are multiples of 3 and 5 are the multiples of the lowest common multiples (lcm) of 3 and 5 which is 15. The multiples of 15 between 10 and 50 are {15, 30 and 45}, thus there are 3 numbers.
There are 720 of them.
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......
Multiply 35 by the first three counting numbers. That will give you the first three multiples. To be common, they need to be compared to another set of multiples. If you meant 3 and 5, the LCM is 15. Multiplying 15 by 2 and 3 will give you the others.
