Problem

Find the largest commom factor numbers-16,24.

Hint

The largest common factor of two numbers is also known as the greatest common divisor (GCD).

Step

To find the GCD of 16 and 24, we can use various methods, such as prime factorization or listing factors.

Step

Here’s the prime factorization method for 16 and 24:

Step

Prime factorization of 16:

16 = 2 × 2 × 2 × 2

Step

Prime factorization of 24:

24 = 2 × 2 × 2 × 3

Step

Identify the common prime factors:

2, 2, and 2

Step

Multiply the common prime factors together:

2 × 2 × 2 = 8

Step

So, the greatest common divisor of 16 and 24 is 8.

Sumup

Can you summarize what you’ve understood in the above steps?

Choice.A

The common factors of 16 and 24 include 1, 2, and 4, but not 6. Therefore, option A is incorrect

Choice.B

This is incorrect as it does not represent the largest common factor of the two numbers

Choice.C

The number 16 is not divisible by 3, so option C is incorrect

Choice.D

This is correct because 8 is the largest number that divides both 16 and 24 without leaving a remainder
