First, all numbers are divisible by themselves and 1. If a number is even, one of the factors is 2, and another is whatever 2 needs to multiply with to get the number. Then, If the sum of the digits (in this case, 7 + 2 = 9) is divisible by 3, one of the factors is 3, and another is whatever 3 needs to be multiplied by to get the number.

After that, try dividing by four. If the product is a whole number, then 4 is one of the factors along with whatever 4 needs to multiply with to get the number. The same process can be followed with the rest of the numbers 5 through 10. If the answer is a whole number, two factors have been identified.
