To find the Highest Common Factor (HCF) of 18 and 48 using the division method, you can follow these steps:
- Divide the larger number by the smaller number: Start with the two numbers, which are 48 and 18. Divide 48 by 18.
- Calculate the quotient and remainder:
When you divide, you calculate:
48 ÷ 18 = 2 remainder 12
This means that 48 can be expressed as:
48 = (18 × 2) + 12
- Now, take the divisor (18) and the remainder (12): Next, repeat the process by dividing the previous divisor (18) by the remainder (12).
- Repeat the division:
18 ÷ 12 = 1 remainder 6
This means:
18 = (12 × 1) + 6
- Continue the process: Now take 12 and divide it by the new remainder (6).
- Perform the division:
12 ÷ 6 = 2 remainder 0
Thus:
12 = (6 × 2) + 0
- Determine the HCF: When you reach a remainder of 0, the divisor at that step is the HCF. Here, since the last divisor is 6 and the remainder is now 0, the HCF of 18 and 48 is 6.
In summary, the HCF of 18 and 48 using the division method is 6.
