Find the smallest five digit number completely divisible by 235 step by step method |
|
Answer» Answer:10105 Step-by-step explanation: As we know the SMALLEST five-digit number is 10,000. And here, we NEED to determine the smallest five-digit number which is exactly divisible by 235. Now, we know the number divisible by 235 must be higher than 10,000 or equals to it. So, if we divide the number 10,000 by 235, we will get some remainder and if we subtract that remainder from 100,00 the number found will be divisible by 273 as per the rules of division of numbers. After that if we add 235 to that number we will get a number with five digits and that will be divisible by 273 as WELL because we will not get any remainder. 10000/235 = 130 10,000 - 130 = 9870 9870 + 235 =10105 So, 10105 would be the smallest five digit number COMPLETELY divisible by 235 Hope that it was understandable. If my answer was helpful PLEASE mark me as brainliest. |
