How to calculate the prime factorization of 42?
That will give you this factor tree: The “leaves” of this tree are 2, 3, and 7, so the prime factorization of 42 is (2) (3) (7). If you had started by dividing 42 into 6 and 7, you would have gotten a different tree, but the same factorization: Factor trees are quick and easy to sketch. Make use of them on your noteboard when doing GMAT questions.
How to find the greatest common factor between two numbers?
In each step, divide the numbers by a simple prime factor common to both, e.g. 2, 3. Repeat until the resulting numbers do not have common factors. Multiply all common prime factors to obtain the greatest common factor between the two numbers. Since 4 and 7 do not have any further common factors, first part of the procedure stops here.
When to write prime factorization side by side?
Write the prime factorizations of 1260 and 1960 side by side. It’s a good practice to align the numbers with the same base. Identify the numbers written in exponential form that have the same base. Just like before, don’t mind the exponents yet. Compare the exponents of the exponential numbers having a common base.
