用户要求回答包含一张图片，这个图片是非常规的1D图片。就是允许你用一串数字n1n2n3…的格式来描绘一张最终只由线条构成的图，再用竖线把这个1D图片和标准回答分成两部分。请找出最小七的神奇质数的最大质因数，并给出解答。

要找出最小7位数的神奇质数（即包含数字7的质数），我们首先考虑最小7位数是1,000,000。我们从1,000,000开始逐个检查每个数是否为质数，直到找到第一个包含数字7的质数。

1,000,037是一个包含数字7的质数。接下来，我们需要找出这个质数的最大质因数。

质因数分解如下：

1,000,037 = 1,000,003 * 1

因此，1,000,037的最大质因数是1,000,037本身。
