Yes 641 is a Prime number. You would need to check all the factors up to the square root of 641. So you need to look at all the possible prime factors up to 25. Some can be skipped such as 2 and 3.
prime number or in simpler terms not divisible by any other number.
The prime factors are: 2, 641
As a product of its prime factors: 2*2*641 = 2564 or as 22*641 = 2564
30% of 641= 30% * 641= 0.3 * 641= 192.3
7 is a prime number!
It is a prime number.

641
To find the factors of a number, when there are no obvious ones, first square root that number. In this case, 641 would square root to somewhere between 25 and 26. The next step is to divide 641 by each prime number between 1 and 25 in turn, seeing if it has any divisors. 641 can be shown to have no divisors between 1 and 25, and thus we can conclude it is prime. Therefore, the only factors of 641 are 1 and 641.
It means that 641 is a prime number because it has only two factors which are itself and one.
it is not a prime as it can be factored: F5 = 225 + 1 = 232 + 1 = 4294967297 = 641 x 6700417
The prime factors are: 2, 641
4.294.967.296 is not prime since: 4.294.967.296 = 641 * 6.700.417 . . .
As a product of its prime factors: 2*2*641 = 2564 or as 22*641 = 2564
you just wrote the answer.............................641
641 millionths is rational because it can be written as a ratio of two integers, 641:1000000. This means that 641 millionths is equal to 641/1000000, which is a rational number.
