Why 1 is not prime no ?

Maths Tricks , short cut tricks for maths to make calculation easy and fast

Why 1 is not prime no ? If one is allowed as a prime, then any number could be written as a product of primes in many ways.: Example.
24 = 1*2*2*2*3
or 24 = 1*1*2*2*2*3
or 24 = 1*1*1*1*1*2*2*2*3

The fact that factoring into primes can only be done in one way is important in mathematics.; Is this maths trick helpful? (884) (289) Post / Read comment (0)

Maths Quotes

Pure mathematics is the world's best game. It is more absorbing than chess, more of a gamble than poker, and lasts longer than Monopoly. It's free. It can be played anywhere - Archimedes did it in a bathtub.

Small minds discuss persons. Average minds discuss events. Great minds discuss ideas. Really great minds discuss mathematics.
