At least a T suffix of zero in the B-binary, the largest B.idea: It is easy to think of a number by which the maximum exponent can be obtained by factorization factor. So the key is to get n!. The index of the factor of the element, find all the elements of the exponent greater than T, and then remove the index T, the remaining number is the largest B. When the factori

The maximum common factor is calculated by using the least common multiple method, and the formula is used to seek it.Maximum male factor * least common multiple = two number product The maximum common factor can be solved using recursion and non-recursion, the factorization is basically using a value less than the input number as a divisor, to divide the input value, if you can divide it as a factor, the faster solution is to find less than the numbe
