WebThe Highest Common Factor (HCF) of two or more numbers is the greatest of all their common factors. Therefore, it is also called the greatest common factor (GCF). If we say M is the highest common factor of N, then M is the highest possible number that divides the number N. For example, the common factors of 12 and 16 are 1, 2 and 4. WebThe second method to find GCF for numbers 36 and 90 is to list all Prime Factors for both numbers and multiply the common ones: All Prime Factors of 36: 2, 2, 3, 3. All Prime Factors of 90: 2, 3, 3, 5. As we can see there are Prime Factors common to both numbers: 2, 3, 3. Now we need to multiply them to find GCF: 2 × 3 × 3 = 18.
