Number theory

[caledonia]

I seek a proof, (using the properties of the h.c.f.),  that if k divides nr then k = k₁k₂  where k₁ divides n and k₂ divides r

[mathematic]

Use fndamental theorem of arithmetic.

Well, as a layman, it would seem that if [k] = [k1k2], then [k] = [2] itself, as [1] * [2] = [2]. This is just speculation, let's get more intense?

If the [k] = prime and divides into [k2], then six would be the lowest figure of the range, as the lowest figure for [k1] would be [3], as the lowest prime, so, we could run a log of [3] to find the 'ratios' of one to two, of course. this would follow, basically, that if [k1] = [3], then [k2] = [6], and k = [18], and that [k1] would actually be [k/3], and, that [k2] would be [k/2].

So, if [k=18] as [k=3=18] then [n] would be [k/3].

But, I am just a layman in this vast world.
