Numbers up to 200 divisible by both 2 and 3 = numbers to 200 divisible by 2*3 = 6 which is int(200/6) = int(33.33) = 33
Oh, dude, let's break it down. So, first, you gotta figure out how many numbers are divisible by 3, right? Then, do the same for 7. But, here's the kicker - you gotta remember to subtract the numbers divisible by both 3 and 7. It's like a math puzzle, but with numbers. So, like, get your calculator out and have fun with it.
Divisible by both? 2 numbers... 45 and 90
To find the natural numbers below 30 that are divisible by both 3 and 2, we need to determine numbers that are divisible by their least common multiple (LCM), which is 6. The natural numbers below 30 that are multiples of 6 are 6, 12, 18, and 24. Therefore, there are 4 natural numbers below 30 that are divisible by both 3 and 2.
Two numbers: 126 and 147
Four. 24 and its multiples.
670
20 of them.
Numbers that are divisible by both 6 and 7 must be divisible by the least common multiple of 6 and 7, which is 42. Therefore, the numbers divisible by both 6 and 7 are multiples of 42. This includes numbers like 42, 84, 126, and so on.
