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.
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.
