Answer 1

Finding Divisors of Numbers

To find the divisors of a number, we need to determine the numbers that divide it evenly without leaving a remainder. Let's start by finding the divisors of the given numbers.

For the numbers 2, 3, 5, 12, 18, 20, and 22, we need to identify the divisors that divide them evenly. Here are the divisors for each number:

- Divisors of 2: 1, 2 - Divisors of 3: 1, 3 - Divisors of 5: 1, 5 - Divisors of 12: 1, 2, 3, 4, 6, 12 - Divisors of 18: 1, 2, 3, 6, 9, 18 - Divisors of 20: 1, 2, 4, 5, 10, 20 - Divisors of 22: 1, 2, 11, 22

Now let's move on to the next set of numbers.

For the numbers 1, 6, 8, 10, 16, and 20, we need to find their divisors. Here are the divisors for each number:

- Divisors of 1: 1 - Divisors of 6: 1, 2, 3, 6 - Divisors of 8: 1, 2, 4, 8 - Divisors of 10: 1, 2, 5, 10 - Divisors of 16: 1, 2, 4, 8, 16 - Divisors of 20: 1, 2, 4, 5, 10, 20

Numbers Divisible by 3 and 6

To find all the numbers from 1 to 99 that are divisible by both 3 and 6, we can check each number in that range and see if it satisfies the condition.

Here is the list of numbers from 1 to 99 that are divisible by both 3 and 6:

3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99

Finding a Number Divisible by 3 and 7

To find a number that is divisible by both 3 and 7, we can start by finding the least common multiple (LCM) of 3 and 7. The LCM of two numbers is the smallest number that is divisible by both of them.

The LCM of 3 and 7 is 21. Therefore, any multiple of 21 will be divisible by both 3 and 7. Let's choose a multiple of 21, such as 42, which is divisible by both 3 and 7.

So, the number that replaces Y in "14Y" to make it divisible by both 3 and 7 is 42.
