15, 30, 45, 60, 75, 90
15, 30, 45 and so on to infinity.
1100, 2200, 3300, 4400, 5500.
Infinite. Here are the first five: 1100, 2200, 3300, 4400, 5500.
They are all multiples.
multiples of 275 are: 550, 825, 1100, 1375, 1650, 1925, 2200, 2475, etcThere are of course, an infinite number of multiples.
220, 440, 660, 880, 1100, 1320, 1540, . . .
550, 1100, 1650, 2200, 2750, 3300, 3850, . . .
Those are known as "common multiples". The smallest POSITIVE of these common multiples is called the "least common multiple".
CJ:there are no common multiples for 25
All multiples of 840 are common multiples of 60 and 280
the common multiples are most all of the multiples of 8
uhhhhh
