Let's see . . .
(100 numbers) x (30 multiples for each number) = an answer with 3,000 parts to it
the common multiples of 20 and 25 is 100 (through 100)
All numbers have an infinite amount of multiples.
The greatest multiple of 6 that's less than 100 is (16 x 6) = 96.Since that's the 16th multiple of 6, there are 16 of them less than 100,which is 16% of the numbers from 1 to 100.
the multiples of one hundred is 100,200,300,400,500,600,700,800,900, and so on.
8,16,24,32,40,48,56,64,72,80,88,96
There are floor(100/8)=12 multiples of 8 between 1 and 100. 12/100*100=12%
the common multiples of 20 and 25 is 100 (through 100)
Every number has 1 as a multiple. 1*100 = 100 1*7 = 7 As 1 is an odd number there are no numbers with only even multiples.
All of those numbers have an infinite number of multiples.
25%
The 3-digit counting numbers are 100 through 999 = 900 numbers.Half them are multiples of 2 (even numbers).The other half are not . . . 450 of them.
Multiples of 100.
All numbers have an infinite amount of multiples.
101
200 and 300 are multiples of 100, among many others.
101
There are 166 multiples of 6 in that range. There are 100 multiples of 10 in that range. There are 33 numbers on both lists. 266 - 33 = 233
