Decompose a natural number into prime factors, if the sum of the digits of each digit of all prime factors is equal to the sum of the digits of each digit of the original number, then such a number is called "Smith book number" such as: 27=3*3* 3.3+3+3=2+7, that is, 27 is the Smith number, then, in 4, 32, 58, 65, 94, how many Smith numbers are there?
把一个自然数分解质因数，若所有质因数每个数位上的数字的和等于原数每个数位上的数字的和，则称这样的数为"史密斯书数"如：27=3*3*3.3+3+3=2+7，即27是史密斯数，那么，在4，32，58，65，94中，史密斯数有多少个．
