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.
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
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= 1212 is divisible by 3.
It is not evenly divisible.
No.
21789 is divisible by 1, 3, 9, 27, 81, 269, 807, 2421, 7263, 21789
To determine if 2421 is divisible by a certain number, we need to check if the remainder when 2421 is divided by that number is zero. For example, 2421 ÷ 3 = 807 with no remainder, so 2421 is divisible by 3. However, 2421 is not divisible by 2, as 2421 ÷ 2 = 1210 with a remainder of 1. Similarly, 2421 is not divisible by 5, as 2421 ÷ 5 = 484 with a remainder of 1.
To determine if 807 is prime or composite, we can check if it has any factors other than 1 and itself. By dividing 807 by all numbers less than its square root (28.4), we find that it is divisible by 3 and 269 in addition to 1 and itself. Therefore, 807 is a composite number.
The positive integer factors of 807 are: 1, 3, 269, 807
The factors of 807 are: 1, 3, 269, and 807.The prime factors of 807 are: 3 and 269.
