To answer this, just use a spreadsheet, and put in {cell A1} 3, then in {cell A2} put '=A1+3', then just copy down to {cell A16666} Since 3 x 16667 = 50001. If you don't own a spreadsheet, Google Docs has a free online one, or OpenOffice is a free one to install on your computer.
You will have {3, 6, 9, 12, 15, ...., 49992, 49995, 49998}
The multiples of 4 up to 30 are: 4, 8, 12, 16, 20, 24, 28.
It's not. 4 is a multiple of 2. 2 is a factor of 4 because it can divide into 4 evenly with no remainder.
4 could only go up to 52 or 48, you could not get to 50 by just multiplying 4 by other whole numbers
Four has an infinite number of multiples.
Since 4 is a multiple of 2, all the multiples of 4 will be common.
No odd numbers are multiples of 4.
Look at the multiples of 6. The smallest and greatest multiples of 6 that can be divided evenly by 4 are 12 and 48. So the common multiples of 4 and 6 up to 50 are 12, 24, 36, and 48.
4,8,12,16,20,24,28,32,36,40
12500
250
4,8,12,16,20
12500
There are 125 such numbers.
The numbers up to 12 are 4,8,12,16,20,24,28,32,36,40,44,48.
The multiples of 4 up to 30 are: 4, 8, 12, 16, 20, 24, 28.
4/5 of 50000 = 40000
0.04 of 50,000 = 4% of 50,000 = 2000
