The greatest comment factor of 28 and 64 is 4.

The factors of 28 are 28, 14, 7, 4, 2, 1.
The factors of 64 are 64, 32, 16, 8, 4, 2, 1.

The common factors of 28 and 64 are 4, 2.

the greatest one of the two factors is 4.

Another way to find GCF is by the euclidean algorithm. Even though the name sounds intimidating, it is probably the easiest method, especially if the numbers are large.

The method consists of calculating the difference of the two given numbers. Then among the two numbers and the difference, repeat with the two smaller numbers until the difference is zero. The smallest surviving number is then the GCF.

As an example for 64 and 28.

64-28=36. Choose the smaller two numbers and repeat

36-28=8 Choose the smaller two numbers and repeat

28-8=20 Choose the smaller two numbers and repeat

20-8=12 Choose the smaller two numbers and repeat

12-8=4 Choose the smaller two numbers and repeat

8-2*4=0 therefore 4 is the GCF.

As a short-cut, when the larger number is much larger than the smaller, we can subtract a multiple of the smaller number. Example again using 64 and 28.

64-28=36

36-28=8

28-3*8=28-24=4

8-2*4=0 Therefore 4 is the GCF of 64 and 28.

As a more adventurous example, let's find the GCF of 3888 and 3774.

3888-3774=114

3774-30*114=354

354-3*114=12

12-8*12=6

12-2*6=0 Therefore 6 is the GCF of 3888 and 3774.

9741 divided by 221 in fraction form
babymother [125]
We want the GCD of 9741: 3 * 17 * 191. In order to get that...
9741 is divisible by 3 and equal to 3247  * 3 therefore we have 3 * 3247.
3247 is divisible by 17 and equal to 191 * 17 therefore we have 3 * 17 * 191, these are all prime numbers so no more factorization for this part.

Now we need to prime factorize the 221.
221 is divisible by 13 and equal to 17 * 13 therefore we have 13 * 17 which are all prime numbers meaning no more factorization.

Now we want to factor out 17 from the numerator/denominator

9741 = 17 * 573
221 = 17 * 13

In other words...(Same thing cancel the common factor of 17)
\frac{17 * 573}{17 * 13} =  \frac{573}{13}

Find the area enclosed by the x-axis and the curve x = 4 + et, y = t − t2.
Dominik [7]

Find where the curve intersects the <em>x</em>-axis; this happens when <em>y</em> = 0:

<em>y</em> = <em>t</em> - <em>t</em> ² = 0   →   <em>t</em> (1 - <em>t</em> ) = 0   →   <em>t</em> = 0, <em>t</em> = 1

Then the area of the bounded region is

\displaystyle\int_0^1 y(t) x'(t)\,\mathrm dt=\int_0^1 (t-t^2)e^t\,\mathrm dt=\boxed{3-e}

(you can compute the integral by parts)
