Answer:

Greatest Common Factor of 18 and 24

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

GCF(18,24) = 6

We will now calculate the prime factors of 18 and 24, than find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 18 and 24.

Step-by-step explanation:

Answer:

The HCF of the given pair is 6.

Step-by-step explanation:

The HCF, or the highest common factor, or 2 numbers is basically the largest number dividing 2 or more numbers.

To find out the HCF of a pair of numbers, we need to perform prime factorization on them, followed by grouping the factors, and finding the highest factor common to them.

Given - a pair of numbers (18, 24)

To find - the pair’s HCF

Solution - We need to first prime factorize them

18 = 2 \times 3 \times 3 = 2^1 \times 3^2

Factors - 1, 2, 3, 6, 9 (out of which, 2 and 3 are prime numbers)

24 = 2 \times 2 \times 2 \times 3 = 2^3 \times 3^1

Factors - 1, 2, 3, 4, 6, 8, 12 (out of which, 2 and 3 are prime numbers)

Thus, the common (greatest) factor between the two numbers is 6.

Thus, the HCF of the given pair is 6.
