To find the numbers less than 10,000 that are divisible by 21, 35, and 63, we need to find the least common multiple (LCM) of these three numbers, which is 441. Then, we divide 10,000 by 441 to find how many multiples of 441 are less than 10,000, which is approximately 22. So, there are 22 numbers less than 10,000 that are divisible by 21, 35, and 63.
Eight of them.
Only the multiples of 1000.
The nearest number whose square ≤ 10000 is 100. Then the greatest odd number less that 100 is 99 so there are 50 odd numbers in the range 1- 99 inclusive whose squares are less than 10000.
There are 1229 prime numbers that are less than 10000.
