See if you can find a whole number "n", such that 7n (i.e., 7 times n) = 45. If you can find such a number, then 45 is a multiple, by definition. Otherwise it is not.

To convert the number 45 to base 7, we need to find the largest power of 7 that is less than or equal to 45. In this case, 7^2 is 49, which is greater than 45. So, we will have a digit in the 7^2 place. The largest multiple of 7^2 that is less than 45 is 36 (7^2 * 1), leaving a remainder of 9. The largest multiple of 7 that is less than 9 is 7*1, leaving a remainder of 2. Therefore, 45 in base 7 is represented as 126.
45 is a multiple of 3. 45 is a multiple of 5. 45 is not a multiple of 33. 3 x 3 x 5 = 45
45 is a multiple of both 15 and itself, so 45 is the least common multiple of 15 and 45.
Well, let's take a look at this happy little math problem. If we divide 45 by 7, we find that it equals 6 with a remainder of 3. Since there is a remainder, 45 is not a multiple of 7. Don't worry, mistakes are just happy little accidents along the way to learning something new.
Any multiple of 45.
Yes, 45 is a multiple of 15.
Yes, 123456789 is a multiple of 3. To find out if it's a multiple of 3, you add the digits. In this case you would add 1+2+3+4+5+6+7+8+9=45. Now you take that 45 and divide by 3. If there is no remainder it is a multiple but if there is a remainder it is not a multiple. So in this case 45/3=15 with no remainder.
The least common multiple of 45 , 3 , 5 = 45
The Least Common Multiple of 45, 3, and 5 is 45.
