We will use the formula to find the LCM of 306 and 657. LCM (a, b) = (a × b) / HCF (a, b) Given two numbers 306 and 657 and their HCF is 9. To find : LCM(306,657 ) using the formula, We have LCM (306, 657) = (306 × 657) / HCF (306, 657) = 201042 / 9 = 22338 Thus, LCM of 306 and 657 is 22338

Sia ? 4 years, 4 months ago

Given:

An army contingent of 612 members is to march behind an army band of 48 members.

Here, HCF of 612 and 48 will give the maximum number of columns in which the two groups can march.

So, using Euclid's division algorithm

612=48×12+36

⇒48=36×1+12

→36=12×3+0

∴HCF(612,48)=12

Hence, the maximum no of columns in which they can march is 12

Show that any positive integer is of the form 3q, 3q+1, 3q+2, where q is some integer

Posted by Arpan Narain 4 years, 4 months ago

Preeti Dabral 4 years, 4 months ago

Let p be any positive integer and b = 3. Applying division Lemma with p and b =3 ,

we have
p = 3q + r, where 0 {tex}\leq{/tex} r < 3 and q is some integer

So r=0,1,2

If r=0 , p=3q

If r=1, p=3q+1

If r=2, p=3q+2

Therefore any positive integer is of form 3q,3q+1,3q+2 for some integer q.
