What do you notice about common multiples of 2 and 3?
They are all multiples of 6
What are the multiplies of the number 8?
3 multiples and they are all 2 2 * 2 * 2 = 8
What is multiples by 2?
All the even numbers are multiples of 2
What are the multiples of 3 5 and7?
Since all 3 are prime numbers LCM = 3 * 5 * 7 = 105 All multiples of 105 are multiples of 3, 5 and 7
What are multiples of 2 and 4?
They are all the multiples of 4.
Multiples of 2 3 4 an 5?
Any and all multiples of 60.
The common multiples of 2 and 6?
Since 2 is a multiple of 6, all multiples of 6 are also multiples of 2.
What are all the multiples of -3 and 2?
There is an infinite number of these...
What are the common multiples of 2 3 and 15 that are lower then 100?
They have to be multiples of 15 so all of them will be multiples of 3. They all have to be even so you are left with 30, 60, 90
Are all multiples of 3 odd why?
No, because 3 x 2 = 6
How many numbers from 1 to 100 are multiples of 2 3 4 6 8 9?
Assuming you mean that you want the number of multiples of each, then for 1-100: number of multiples of 2 = 50 number of multiples of 3 = 33 number of multiples of 4 = 25 number of multiples of 6 = 16 number of multiples of 8 = 12 number of multiples of 9 = 11 Assuming you mean that you want the numbers that are multiples of 2, 3, 4, 6, 8 or 9, then some numbers may be multiples of more than one (for example 12 is a multiple of 2, 3, 4 and 6) and so a straight addition of the number of multiples of each cannot be done: Consider 2, 4 and 8 Every multiple of 4 or 8 is also a multiple of 2, so all the multiples of 4 and 8 are counted by the multiples of 2. Consider 3 and 9 Every multiple of 9 is also a multiple of 3, so all the multiples of 9 are counted by the multiple of 3 Consider 2, 3 and 6. Every multiple of 6 is an even multiple of 3, so are counted in both the multiples of 2 and 3. So the total number of multiples of 2, 3, 4, 6, 8 or 9 is the number of multiples of 2 plus the number of multiples of 3 minus the number of multiples of 6: For 1 to 100, Number of multiples of 2 = 50 Number of multiples of 3 = 33 Number of multiples of 6 = 16 So number of multiples of 2, 3, 4, 6, 8 or 9 in 1-100 is 50+33-16 = 67. Assuming you mean that they are multiples of all of 2, 3, 4, 6, 8 and 9, then they must be multiples of the lowest common multiple of 2, 3, 4, 6 ,8, 9 2 = 21, 3 = 31, 4 = 22, 6 = 2131, 8 = 23, 9 = 32 LCM = highest power of the primes used = 2332 = 72 Thus all numbers that are multiples of 2, 3, 4, 6, 8 and 9 are multiples of 72, which means between 1 and 100 only 1 number is a multiple of all of them, namely 72
What multiples of 2 is a factor of 3?
No multiples of 2 are factors of 3.
All multiples of 3?
3,6,9,12,15,18,21,24,27,30,33,36,39,42,45,48,51,54,57,60,63,66,69,72,75,78,81,84,87,90,93,96,99,102All the multiples of 3.
Why are 8 multiples are fewer than multiples of 2?
All multiples of 8 are also multiples of 2, but not all multiples of 2 are multiples of 8.
What are 3 numbers with only even multiples?
2, 4, 6 All even numbers have even multiples.
What is the sum of all 2-digit multiples of 5?
-3
Does a natural number have unlimited number of multiples?
Yes, for example the multiples of 2 are: 2, 4, 6, 8, 10, 12, 14, ......etc. (all even numbers are multiples of 2) or multiples of 3 are 3, 6, 9, 12, 15, 18, 21, ....... etc.
