Well, to find out if any number is divisible by 3, you add up the number's factors. If the number you come up with is divisible by 3, then the entire number is divisible by 3.
For example:
138= 1+3+8= 12
12 is divisible by 3.
Composite since it ends in an even number it will always be divisible by 2
Suppose x = sqrt(3*a) where a is an integer that is not divisible by 3. then x2 = 3*a which is divisible by 3. but x is not even rational and so is not an integer and is certainly not divisible by 3.
12345 is divisible by 3 and the answer is 4115
To determine if 42 is divisible by 3, you can add up the digits of 42 (4 + 2 = 6) and check if the sum is divisible by 3. Since 6 is divisible by 3, then 42 is also divisible by 3. This is based on the rule that a number is divisible by 3 if the sum of its digits is divisible by 3.
2 x 3 x 23 = 138
138 is divisible by 6. Any number is divisible by 6 if it is an even number that also is divisible by 3.
Yes. 138 is evenly divisible by three.
It is, but it is NOT evenly divisible.
138 is not divisible by 18.
138 / 9 is equal to 15.33 or 15 with remainder 3.
Yes. The result is 46.
No. 138 is divisible by 2.
No - 138/4 = 34.5
No.

I think the question is mistyped, and should be "Is 414 evenly divisible by 3?" i.e. does it divide by 3 without leaving a remainder. The answer is yes. A quick way to tell if a number is divisible by 3 is to add the digits and if the total is divisible by 3, then the number in question is also divisible by 3 4 + 1 + 4 = 9 and 9 is divisible by 3 414 ÷ 3 = 138
Yes. 276 is divisible by these numbers: 1 2 3 4 6 12 23 46 69 92 138 and 276.
