to answer a Prime number you must find a number that goes into it and that divides by itself :)
13 is a prime number. The only prime factor of a prime number is the number itself.
You cannot "solve" a single number!
The prime factors of 100 are 2 and 5; the largest of these is 5. The largest prime number under 100 is 97.
67 is a prime number because it has only two factors which are itself and one.
What problem?
Using supercomputers and very clever programming.
prime
I think you mean that the prime factorization is 2 times 3 times 5. To solve, just perform the multiplication: 2x3x5=30
12233
12q 12,q 6,2,q 3,2,2,q
when we multiply any number of decimals method it goes by the prime factor method
In general, you cannot. If the number in scientific notation has not been rounded then express it is normal form and proceed from there.
