What are some tips to apply prime factorization to whole numbers

The video tutorial explains how to approach prime factorization by identifying divisibility rules. It emphasizes starting with even numbers, which can be divided by two, and then moves on to numbers ending in 5 or 0, which are divisible by five. For odd numbers, it suggests checking divisibility by common odd numbers like 3, 9, and 7. The tutorial provides practical tips for efficiently breaking down numbers into their prime factors.
