Which is the HCF of 30 and 42?
When you get the remainder zero then that divisor i.e., 6 is the HCF of given numbers. Thus, HCF of 30 and 42 is 6. If you want to explore more about the HCF, GCF, LCM, Prime Factorization, etc. then visit lcmgcf.com and learn all these concepts clearly.
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.
The greatest common factor is either the difference between the numbers or a factor of the difference between the numbers. Note: 84 – 63 = 21 and 63 – 42 = 21. So, the greatest common factor might be 21. When you divide each of the numbers by 21, it divides evenly, so 21 is the greatest common factor.
