A, B, and C each have a number of apples in their hands. Now A distributes part of the apples in his hand to B, so that the number of apples in B becomes twice the original number. After B gets the apples, he distributes part of the apples in his hand to C, so that the number of apples in C becomes the original number. 2 times. In this way, there are as many apples in the hands of the three people. In the process of subdividing, each person has an integer number of apples. So what is the total number of apples in the hands of the three people at least?
甲乙丙三人手中各有苹果若干个．现在甲把手中苹果的一部分分给乙，使得乙的苹果个数变为原来的2倍，乙在得到苹果之后再将手中的苹果的一部分分给丙，使得丙的苹果个数变为原来的2倍．这样一来，3人手中的苹果就一样多了．如果再分的过程中，每人手中的苹果都是整数个．那么三人手中的苹果总数至少是多少个．
