The common multiples of 6 and 5 are 30, 60, 90, 120, 150, 180, and so on.
Multiples of 6 are.
6 of them.
The slot from -150 to 350 is 500 wide. 500/6 = 831/3 -150 is a multiple of 6, and there are 83 more on the way to 350.
That's the same as asking how many multiples of 12 are between 1 and 150 and since 12 x 12 = 144, your answer is 12.
The common multiples of 5 and 6 are the multiples of their lowest common multiple (which is 30), so there are infinitely many common multiples of 5 and 6. The first five are: 30, 60, 90, 120, 150.
There are 83 multiples of six that fall between 500 and 1,000.
150, 300, 450, 600, 750, 900.
117 of them.
Oh, dude, you're really making me use my brain cells for this one. So, between 1 and 100, there are no even numbers that are multiples of 3. I mean, like, it's just not a thing. So, the answer is a big fat zero. But hey, at least now you know, right?
There are 67.
Just count the multiples of 6...
There are 10 multiples of 6 in that range.
There are 6 because 6*15 = 90
