There are 50 consecutive natural numbers. The first one is a and the last one is a

There are 50 consecutive natural numbers, the first is a, and the last is a + 49

If 〈 a 〉 represents the number of factors of natural number A. for example, 4 has three factors of 1, 2 and 4, which can be expressed as 〈 4 〉 = 3. Try to find the value of (〈 18 〉 + 〈 22 〉) △ 7 〉

The factor of 18 has 1,2,3,6,9,18, so there are six factors, so the factor of = 6,22 has 1,2,11,22. So there are four. That is, the factor of ＜ 22 ＞ = 4.7 is 1,7. It is two. That is ＜ 7 ＞ = 2, so the original formula = (6 + 4) △ 2 = 5

In 1999, how many natural numbers are multiples of 3 and 5

It's a multiple of 3, and it's a multiple of 5, which is a multiple of 3 × 5 = 15
1999 △ 15 = 133 + 4
So it's a multiple of 3 and a multiple of 5, 133

How many natural numbers from 1 to 1999 are multiples of 3 and 5?

The multiple of five is nineteen thousand nine hundred
There are 666 multiples of three
