To find prime numbers less than 100, the sieve of eratosthenes filters out 1 and all multiples of 2, 3, 5, and 7. All remaining numbers less than 100 are primes.
There are ten different integral multiples of 10 that are equal or less than 100.
Multiples of 100 are numbers that can be divided evenly by 100. To find the multiples of 100 between 7806 and 8206, you need to find the smallest multiple of 100 greater than or equal to 7806 and the largest multiple of 100 less than or equal to 8206. The smallest multiple of 100 greater than 7806 is 7900, and the largest multiple of 100 less than 8206 is 8200. Therefore, the multiples of 100 between 7806 and 8206 are 7900, 8000, and 8100.
The multiples of 5 that are also multiples of 6 are multiples of their LCM. The LCM of 5 and 6 is 30, so the question becomes which multiples of 30 are less than 100? The solution is the numbers: 30, 60, 90
