Euclidâ€™s division algorithm can be applied to :
Euclidâ€™s division algorithm can be applied only to positive integers.
For some integer m, every even integer is of the form :
Integer are 2, 4, 6, 8â€¦. It can be written in the form of 2m. Where m = integer.
If the HCF of 65 and 117 is expressible in the form 65m â€“ 117, then the value of m is :
HCF
If two positive integers \(p \) and \(q \) can be expressed as \(p=ab^2 \) and \(q = a^3b, a; b\) being prime numbers, then \(LCM\ (p, q)\) is :
LCM

If two positive integers \(p \) and \(q \) can be expressed as \(p = ab^2\) and \(q = a^2b; a, b\) being prime numbers, then \(LCM\ (p, q)\) is :
LCM =
Euclidâ€™s division lemma states that for two positive integers a and b, there exist unique integers q and r such that a = bq + r, where :
Following are the steps in finding the GCD of 21 and 333 :
\(333=21\times m+18\\ \\ 21=18\times1+3\\ \\ n=3\times6+0 \)
The integers \(m \) and \(n \) are :
\((n+1)^21 \) is divisible by 8, if n is :
is divisible by 8 if n is an even integer.
The largest number which divides 71 and 126, leaving remainders 6 and 9 respectively is :
let us subtract 6 and 9 from 71 and 126, i.e.
and
now find the hcf of 65 and 117.
thus the hcf of 65 and 117 is 13 and the required number is 13.
