Answer» 12 )81444 (6787 is the answer of the following ans - 81444 EXPLANATION-------------------------------Divisibility Rule for 12 A number is divisible by 12 if it is divisible by both 3 and 4. The reason this is true is because12 = 3 × 4. Knowing this, the only part that you may not understand is when a number is evenly divisible by 4. This is the case when the last two digits of the number are divisible by four.If you have trouble looking at a two digit number and figuring out if it is divisible by four, try the following: If the right-most digit is odd, it is not divisible by four. If the right-most digit is 0, 4, or 8, the next digit to the left must be even. If the right-most digit is 2, or 6, the next digit to the left must be odd. |
