A number that is divisible by 3 has the sum of its digits divisible by 3. The number 210 satisfies all three conditions so 210 is the answer.我们首先考虑7的倍数来尽可能的减少数字量.在给定的范围内的7的倍数有203,210 ,217, ,294.因为数字必须能被5整除,所以必须以5或0结尾.而又因为一个数...
A number is divisible by 6 if and only if it is divisible by 3? If this is a T-F question, the answer is false. It is true that if a number is divisible by 6, it also divisible by 3. This is true because 6 is divisible by 3. However, the converse -- If a number is divi...
When the number of Eth-Trunk member interfaces is the nth power of 2, load balancing can be made more even. For example, if the number of Eth-Trunk member interfaces is 2, 4, or 8 (which is divisible by 16), the timeslot of the packets sent by each interface is an integer, makin...
