1. HCF by factorisation Method: HCF is the product of common factors of all the numbers. Example: HCF of 24, 48, 60 First find the prime factors of these numbers 2 |24 2|48 2|60 24= 2*2*2*3 2|12 2|24 2|30 48= 2*2*2*2*3 2|6 2|12 3|15 60= 2*2*3*5 3|3 2|6 5|5 HCF= 2*2*3=12 |1 3|3 |1 |1 2. Division Method: Divide the larger number by the smaller number. Now divide the devisor by the remainder. Continue the process till the remainder is zero. Now this last devisor is the HCF of those two numbers. Repeat the process between this HCF and the other number. 48)60(1 48 12)48(4 48 0 12)60(5 60 0 Ans: 12

We will find the continuous division of 20 you can only divide prime nunbers like 2,3,5,7,11,13,17,19,23 and more SOLUTION: 5[13 13[13 Why is it double thirteen? because thirteen is a prime number ANSWER: 20=5x13 If it is double 13 or 5 for an short anwer or we call it exponential form 20=5 2 two is small at the top ,x13 2two is small at the top That's the answer thankyou! and don't stop dividing until you get one!
There are several methods of division, including long division, which involves breaking down the division process into manageable steps; short division, which simplifies the process for smaller numbers; and synthetic division, commonly used for dividing polynomials. Another method is using repeated subtraction, where the divisor is repeatedly subtracted from the dividend until what remains is less than the divisor. Additionally, the division can be visualized with arrays or using a number line for conceptual understanding.
short division is the same thing as long division only shorter. Short division is how many times a number can go into a biger number. as an example 2 goes into 8, 4 times and 9 goes into 9 once and 5 goes into 10, 2 times.

The prime factorization of 14 in exponential form is 21x71.
24 x 5 = 80
2 x 11 x 11 = 242
Index form
Short Division in math is a calculated division in one line. It is different from Long Division which is a method of calculating over a few lines used in calculating big numbers. An example of Short Division would be: 60 / 12 = 5.

7x6x6x7x2x7x6 = 2 x 63 x 73
Short answer: 1. Long anwer: The prime factorization of 8 is 2 * 2 * 2 and the prime factorization of 11 is 11. By the Fundamental Theorem of Arithmetic, the factorization is unique and all common prime factors must appear in both lists (2, 2, 2 and 11). Since no prime divides both 8 and 11, then the only other possible answers are 1 and -1. Because 1 > -1, the answer is 1.
288/4 = 72 using short or long division
I would use short division, though others would use long division, chunking or another method of their choice. ..... 1 2 1 ... ------- 7 | 814 7
