Question: How Do You Find The HCF?

How do you find the HCF factorization?

HCF by Prime FactorizationFind the prime factors of each of the given number.Next, we identify the common prime factors of the given numbers.We then multiply the common factors.

The product of these common factors is the HCF of the given numbers..

What is the HCF of 15 25 and 30?

5The biggest common factor number is the GCF number. So the greatest common factor 15,25,30 is 5.

What is the HCF of 18 24?

6Greatest common factor (GCF) of 18 and 24 is 6.

What is the HCF of 170 and 238?

gcf, hcf, gcd (170; 238) = 34 = 2 × 17: greatest (highest) common factor (divisor), calculated. The numbers have common prime factors.

What is the HCF of 6 and 4?

We found the factors and prime factorization of 4 and 6. The biggest common factor number is the GCF number. So the greatest common factor 4 and 6 is 2.

What is the HCF of 24 and 36?

Factors of 36 = 1, 2, 3, 4, 6, 9, 12, 18 and 36. Therefore, common factor of 24 and 36 = 1, 2, 3, 4, 6, 8 and 12. Highest common factor (H.C.F) of 24 and 36 = 12.

What is the HCF of 36 and 45?

We found the factors and prime factorization of 36 and 45. The biggest common factor number is the GCF number. So the greatest common factor 36 and 45 is 9.
