Numbers
Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

How can the prime factorization of 2 numbers be used to determine their GCF and LCM?
Example: 30 and 42
2 x 3 x 5 = 30
2 x 3 x 7 = 42
Select the common factors.
2 x 3 = 6, the GCF
Combine the factors, eliminating duplicates.
2 x 3 x 5 x 7 = 210, the LCM
How much time it take to count one billion rupees?
It will depend on the denomination(s). For example, it will take a hundred times longer to count in 5 rupee notes than in 500 rupee notes!
Is the product of a mixed number and a mixed number ever a whole number?
Yes. Example:
11/2 x 11/3 = 2
Is there an algorithm that yields only prime numbers?
What exactly do you mean "yields only prime numbers"?
If you mean a formula that when given the numbers n=1, 2, 3, ... and so on generates the nth prime number (or a different prime number for each n) then no.
If you mean an algorithm whereby a number can be tested to be a prime number then yes.
(Using this prime_test algorithm, a simple algorithm can be written that would supply numbers one at a time to it and use its result to decide whether to yield the tested number or not, only yielding those numbers which pass the test.)
Pimarily Homo Sapiens (humans) HOWEVER- there are documented instances of the use of language by gorillas- including the use of sign language.
What number sentence shows the probability of not rolling an even number on a cube?
idk i'm only in 5th grade my guess would be 3
What is it called when the second number is a facotor of the first number?
In that event, the first number is called a "multiple" of the second number.
Why pi is a rational or an irrational number?
Pi is an irrational number because it cannot be expressed as a ratio of two integers.
Who discovered the highest known prime number?
On Jan. 25, 2013, the largest known prime number, 257,885,161-1, was discovered on Great Internet Mersenne Prime Search (GIMPS) volunteer Curtis Cooper's computer. The new prime number, 2 multiplied by itself 57,885,161 times, less one, has 17,425,170 digits.
What makes prime numbers and composite numbers related?
Prime numbers are related with composite numbers as they are both natural numbers and real numbers and also every composite number is a product of prime numbers due to which they are related with each other.For example 24=[2] [2] [3] [2].Here 24 is a composite number,real number and natural number and 2,2,3,2 are prime numbers and also they are real and natural numbers
Yes because all whole numbers are integers which includes 1
