Page 40 - The logarithm of the product of two or more numbers is equal to the sum of the logarithms of those numbers. Let a denote the base of the system ; also, let m and n be any two numbers, and x and y their logarithms. Then, by the definition of logarithms, we have ax=m, (1.) a?in.

Page 49 - Divide the number by any prime number which will divide it without any remainder ; then divide the quotient in the same way, and so continue until a quotient is obtained which is a prime. Then will the successive divisors, together with the last quotient, be the prime factors required.
