How do I find the greatest common factor?

The topic of what's the greatest common factor of 45 and 15 is relevant for anyone interested in mathematics, particularly those who are:

The greatest common factor (GCF) is the largest number that divides both numbers without leaving a remainder. The least common multiple (LCM) is the smallest number that is a multiple of both numbers. While GCF is used to find the largest common factor, LCM is used to find the smallest common multiple.

  • The GCF is always a prime number.
  • Opportunities and realistic risks
