Yes, 321 is divisible by 3 because the sum of its digits (3 + 2 + 1) equals 6, which is a multiple of 3.
12
Yes, yes, and no. 3- sum of digits must be multiple of 3. 6- sum of digits must be multiple of 3 and number must be even (multiple of 2). 9- sum of digits must be multiple of 9. (The sum of the digits here is 21.)
Divisibles by 3 are numbers whose individual digits evenly equal the sum of which is divisible by 3, like 3627 = 3 + 6 + 2 + 7, which equals 18.
Check the sum of the digits, if the sum divisible by 3 then the number is divisible by 3. Example 910: the sum of digits= 9 + 1 + 0 = 10, but 10 is not divisible by 3, so the number 910 is not divisible by 3. Example 2154: the sum of digits = 2 + 1 + 5 + 4 = 12, this sum is divisible by 3, so the number 2154 is divisible by 3. if the sum is long you can check the sum of the sum and apply the same rule. Example 52498731: the sum of digits = 5 + 2 + 4 + 9 + 8 + 7 + 3 + 1 = 39, the sum of the digits for 39 = 3 + 9 = 12, so the original number, i.e. 52498731 is divisible by 3.
1. its even 2.its a number 3.its pretty the sum of its digits times 2 equals 18
12
Yes, 321 is divisible by 3 because the sum of its digits (3 + 2 + 1) equals 6, which is a multiple of 3.
Examples: 111, 1+1+1=3; 12, 1+2=3; 30, 3+0=3.
No. Take 12 for example. 1+2=3 but 1x2 doesn't equal 3, it equals 2.
Yes, it is. Your answer is 406. You can determine whether a number is divisible by 3 by adding the digits. If the sum of the digits (in the above, 1+2+1+8 = 12) equals 3, the number is divisible by 3.
Since a dozen is 12, then the digits are 1 and 2. To get the sum, you simply add 1 + 2, which = 3.
0.1154
A dozen is equal to 12. The sum of the digits of 12 are 1 + 2 = 3.
A factor of a number is an integer that divides the number without leaving a remainder. When the sum of the digits of a number equals 3 or a multiple of 3, it indicates that the number itself is divisible by 3. This is because the divisibility rule for 3 states that if the sum of the digits of a number is divisible by 3, then the number itself is also divisible by 3. Therefore, any factor of a number where the sum of its digits equals 3 or a multiple of 3 will also be a factor of the number itself.
24 divided by three equals 8 divided by four equals 6 2 plus 4 equals 6
Yes, yes, and no. 3- sum of digits must be multiple of 3. 6- sum of digits must be multiple of 3 and number must be even (multiple of 2). 9- sum of digits must be multiple of 9. (The sum of the digits here is 21.)
