For example: highest common factor of 60 and 75 = 15 because 15 is the highest number which divides both 60 and 75 exactly. Similarly, HCF of 24 and 36 is 12, because the common factors of 24 and 36 = 1, 2, 3, 4, 6, 8 and 12.
What is the HCF of 12, 20 and 18?
Find HCF of 12, 20 and 18. Factors of 12 = 2×2×3. Factors of 18 = 2×3×3. Factors of 20 = 2×2×5. The common factors of 12, 18 and 20 are : 2. Hence, 2 is the Highest Common Factor of 18, 20 and 12.

You can enter two or more numbers separated by comma and click calculate, the highest common factor calculator will update you the result.
Which is the highest HCF of 24 and 36?
Similarly, HCF of 24 and 36 is 12, because the common factors of 24 and 36 = 1, 2, 3, 4, 6, 8 and 12. Hence, the Highest Common Factor (H.C.F) of 24 and 36 is 12 and for 24, 36 and 56 it is 4. Hence, 2 is the Highest Common Factor of 18, 20 and 12.
Which is the least common number LCM or GCF?
The numbers also share one copy of 3, one copy of 5, and one copy of 7. Then the GCF is 2 × 3 × 5 × 7 = 210. On the other hand, the Least Common Multiple, the LCM, is the smallest (“least”) number that both 2940 and 3150 will divide into.
Which is the least common multiple of 2940 and 3150?
On the other hand, the Least Common Multiple, the LCM, is the smallest (“least”) number that both 2940 and 3150 will divide into. That is, it is the smallest number that contains both 2940 and 3150 as factors, the smallest number that is a multiple of both these values; it is the multiple common to the two values.
Which is the greatest common factor of 120, 50 and 20?
So, the greatest common factor of 20 and 10 is 10. Therefore, the greatest common factor of 120, 50 and 20 is 10. So, the the greatest common factor of 182664 and 154875 is 177. So, the greatest common factor of 177 and 137688 is 3. Therefore, the greatest common factor of 182664, 154875 and 137688 is 3. [1] Zwillinger, D. (Ed.).
