How do you find the highest common factor with prime numbers?

Here’s how to find the GCF of a set of numbers, using prime factorization:

  1. List the prime factors of each number.
  2. Circle every common prime factor — that is, every prime factor that’s a factor of every number in the set.
  3. Multiply all the circled numbers. The result is the GCF.

How do you find the highest common factor of 12 and 18?

6
The HCF of 12 and 18 is 6. To calculate the Highest common factor of 12 and 18, we need to factor each number (factors of 12 = 1, 2, 3, 4, 6, 12; factors of 18 = 1, 2, 3, 6, 9, 18) and choose the highest factor that exactly divides both 12 and 18, i.e., 6.

What is the HCF of 136 170 and 255?

17
HCF of 136, 170, and 255 is 17.

How do you find the highest common factor using division?

Using Division Method to Find GCF

  1. Step 1 – Divide the larger number by the smaller number using long division.
  2. Step 2 – If the remainder is 0, then the divisor is the GCF.
  3. Step 3 – If the remainder is 0, then the divisor of the last division is the GCF.

What is the HCF of 184 230 and 276?

46
So, HCF of 184, 230 and 276 is 46.

What is the HCF of 255 and 867?

51
The HCF of 867 and 255 is 51.

How to find the greatest common factor-Dummies?

1 Decompose the numbers into their prime factors. 2 Underline the factors that all the original numbers have in common. 3 Multiply the underlined numbers to get the GCF.

Which is the highest common factor of two numbers?

What is the Highest Common Factor? The HCF (Highest Common Factor) of two or more numbers is the highest number among all the common factors of the given numbers. The HCF (Highest Common Factor) of two natural numbers x and y is the largest possible number which divides both x and y.

Which is the greatest factor in both lists?

The number 4 is the greatest number that appears in both lists of factor pairs, so it’s the GCF. Find the greatest common factor of 24, 36, and 42. 6.
