The number is 42 or any multiple of 42.
All of the qualifiers mean the same thing : the number is a multiple, of 2, 3, and 7.
Using the Least Common Multiple:
2 is prime, power is 1
3 is prime, power is 1
7 is prime, power is 1
2 x 3 x 7 = 42

What is the divisibility for 12?
The number in question is divisible by 3 and 4.A number is divisible by 3 if the sum of the digits is divisible by 3.A number is divisible by 4 if the last two digits is divisible by 4.963,411,024divisible by 3 because 48 is divisible by 3 and24 is divisible by 4, therefore 12 is a GO!If the number is divisible by both 3 and 4.then the number is then divisble by 12.The divisibility rule for three is to add up all the numbers in the number- if the number is a multiple of three, then the number you started with is divisible by three. Example- 91 you do 9+1=10, so that (91) is not a multiple of three. Extra example- 21 2+1=3 and three is a multiple of three.The divisibility rule for four is one I made myself- That is if the number is even slip it in half or divide by two, once you have done that check if the number is even- If it is, that number is a multiple of four, if not that number is not. Example- 30 30÷2=15 which is not even, so that means that 30 is not a multiple of four. Extra example- 148 148÷2=74 which is even, so 148 is a multiple of four.If the number is divisible by 3 and four, then it is divisible by 12.Divisible by 3-If all of the digits in the number add up to a multiple of three, then that original number is divisible by threeDivisible by 4-If the last two digits in a number are divisible by four, then that original number is divisible by 4.Example: 36Divisible by 3?3+6= 99/3=3, so it is divisible by three.Divisible by 4?Of course, we know that 36 is divisible by 4 (36/9=4)So 36 is divisible by 4Therefore, we know 36 is divisible by 12
What are the divisibility rules for two and three?
If the number is even, it is divisible by 2. If the sum of the digits is a multiple of 3, the whole number is divisible by 3.
Is 33015 divisible by 3?
Yes 33015/3 is 11005. Here's a tip: if the digits of number add up to a multiple of three, then that number is also a multiple of three.
How would you reconise a multiple of three?
if the number is a 2 or more diget number, you add up all of the numbers in the number and when you have the sum, if the sum is divisible by 3 , the whole number is divisible by three EX. 123=6, 6 is divisible by 3 so 123 is divisible by three 447=15 is divisible by 3 so 447 is divisible by 3 989=26 is *NOT* divisible by 3 so 989 is not divisible by three this truly does work for every single number
What are the multiplies of the number three?
3 6 9 12 15 18 21, etc. Any number that is divisible by three, is a multiple of three. When working with larger numbers, try this shortcut: First add the digits together. If the sum of the digits is divisible by three, then the whole number is divisible by three. For example: 5,844 (5 + 8 + 4 + 4 = 21). 21 is divisible by three; therefore, so is 5844. It is also a multiple three. This shortcut works with any whole number.
