A number is a multiple of n if it is the product of a counting number and n. Factors: If a • b = m, then a and b are factors of m, and m is the product of a and b. Divide the number by each of the counting numbers, in order, until the quotient is smaller than the divisor. Write the composite number as the product of all the primes on the sides and top of the ladder.
