You can use prime factorization to find the GCF of a set of numbers. This often works better for large numbers, where generating lists of all factors can be time-consuming.
Here’s how to find the GCF of a set of numbers using prime factorization:
* List the prime factors of each number.
* Circle every common prime factor — that is, every prime factor that’s a factor of every number in the set.
* Multiply all the circled numbers.
The result is the GCF.
For example, suppose you want to find the GCF of 28, 42, and 70. Step 1 says to list the prime factors of each number. Step 2 says to circle every prime factor that’s common to all three numbers (as shown in the following figure).
As you can see, the numbers 2 and 7 are common factors of all three numbers. Multiply these circled numbers together:
2 · 7 = 14
Thus, the GCF of 28, 42, and 70 is 14.

  • P=₹26,400
  • R=15% p.a compounded yearly
  • n=2 years and 4 months

\tt \: So,amount \: for \: 2 \: years = p \large(1 +  \frac{r}{100}) {}^{n}

\tt=₹26,400 \large(1 +  \frac{15}{100}) {}^{2}

\tt=₹26,400 \:  \large( \frac{23}{20}) {}^{2}

\tt =₹26,400 \times  \frac{23}{20}  \times  \frac{23}{20} \\

\tt = 66 \times 529=₹34,914

\tt \: So,SI \: for \: 4 \: months =   \frac{P \times R \times n }{100 \times 12}

\tt \: =  \frac{ 34,914 \times 15 \times 4 }{100 \times 12} \\

\tt\boxed{ = 1745.70}

Thus,the amount after 2years and 4months =₹34,914+₹1745.70=₹36,659.70

g100num [7]

Answer:

We have

k^2 - 25f^2 + 5kf - 25f^2 =

k^2 - (5f)^2 + 5f( k - 5f) =

( k - 5f )( k + 5f ) + 5f( k - 5f ) =

( k - 5f )( k + 5f + 5f ) =

( k - 5f )( k + 10f );

sashaice [31]

Answer: $20

Step-by-step explanation:

Here os the correct question:

Stephanie saw in an ad in the paper that her favorite kind of perfume was on sale for 25% off. If the sale price was $15, what was the original price of the perfume?

Let the original price of the perfume be y.

Since we are told that 25% is off, that means that 25% has been deducted from the original price. This can be written as:

y - (25% of y) = $15

y - (25/100 × y) = $15

y - 0.25y = $15

0.75y = $15

Divide both side by 0.75

0.75y/0.75 = $15/0.75

y = $20

The original price of the perfume is $20
