Yes.
1 + 2 + 9 = 12 12 is divisible by 3. If the sum of the digits of a number are divisible by 3, then the whole number is divisible by 3. 129 is a composite number because it divisible by a factor other than 1 and itself.
129 is a Composite Number.
It is composite. It is divisible by 3.
129 - 112 = 17
That '8' at the end of it is an immediate tip-off. That tells you that '258' is an even number. All even numbers are composite, because they're all multiples of 2. It so happens that 258 is also divisible by 3, 6, 43, 86, and 129. Any one of these makes it a composite number. But just knowing that it's an even number was enough to tell us that.
The are a number of mathematical operations that gives us the number 129. When you add 100 to 29 you will get 129. Similarly when you subtract 11 from 140, you will get 129.
129 is divisible by three, hence it is a composite number.
129 is a Composite Number.
It is composite. It is divisible by 3.
129 is not a prime number because it has more than two factors and so therefore it is a composite number
129 is divisible by 3. 1+2+9=12 and 12 is divisible by 3. That is the rule of divisibility by 3.
129 - 112 = 17
As an even number greater than 2, 516 is divisible by 2 and therefore composite. Its positive integer factors are: 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
That '8' at the end of it is an immediate tip-off. That tells you that '258' is an even number. All even numbers are composite, because they're all multiples of 2. It so happens that 258 is also divisible by 3, 6, 43, 86, and 129. Any one of these makes it a composite number. But just knowing that it's an even number was enough to tell us that.
After the number 129 comes the number 130. In the decimal number system, each number is one more than the number that precedes it. So, following this pattern, the number that comes after 129 is 130.
The are a number of mathematical operations that gives us the number 129. When you add 100 to 29 you will get 129. Similarly when you subtract 11 from 140, you will get 129.
