What is the greatest common factor of 70 and 100?
The factors of 70 are 1, 2, 5, 7, 10, 14, 35 and 70. The factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50 and 100. So, the Greatest Common Factor for these numbers is 10 because it divides all them without a remainder. Read more about Common Factors below.
Which is the highest HCF of 60 and 75?
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.
Which is the highest common factor in HCF?
As we can note that the mentioned prime factors, on the left side, divide all the numbers exactly. So, they all are common prime factors. We have no common prime factor for the numbers remained at the bottom. So, HCF = 3 × 5 = 15. HCF = 2 × 2 × 3 = 12. Example 3: Find out HCF of 36, 12, 24 and 48. HCF = 2 × 2 × 3 = 12.
How to calculate HCF for a given number?
Step 1: List the prime factors of the given numbers. Step 2: Highlight the numbers that are common in the prime factors of all three numbers. If there is more than one common number, multiply all common numbers to get the HCF. You can verify the answer using the Highest common divisor calculator above.
