V. How to find all the Divisors of a given Number or Quantity. V RULE. 1 J' ''. ' ' Divide the given Quantity or Number by the least of its Divisors that is f i and the Quotient by the least of its Divisors that is C 1, and so on till you have 1 for a Quotient, and you'll have all the prime Divisors of the given Number or Quantity; then multiply each two, three, four, &V. of the prime Divisors into themselves continually, and the several Products are the compound Divisors. Examples. I. So if all the Divisors of 60 were required. First divide it by 2, and the Quotient 30 by 2, and the Quotient 15 by 3, and the Quotient 5 by 5: then the prime Divisors are 1, X, 2, 3, 5; and the Compound ones produe'd by each two are 4, 6, 'io, 15 j by each three are 12, 20, 30 5 by each four (or by all) 60. H II. Again, If all the Divisors of 21 a b b were required. Divide it by 3, and the Quotient jabbbyy, and, jhctDuotient a b b by a, and the Quotient b b by b, and the-Quotient b by b: then the prime Divisors are 1, 3, 7, a, i, b 5 and the Compound ones produe'd by each two are 21, 3 a, 3 bt 7 at' 7 b, ab, b b; by each three, 21 a, 21 b, 3 ab, 3 b b, 7 ab, 7 b1, abb; by each four, ai ab, XI b b, $ abb, 7 abb; and bj all five, 21 abb.
