Where \(k_{1}, k_{2}, \text{and } k_{3} \) are some positive integers \(\begin{array}{l}{a=3 q+r, \text { where } q \geq 0 \text { and } 0 \leq r<3} \\ {\therefore a=3 q \text { or } 3 q+1 \text { or } 3 q+2}\end{array}\) He has made fundamental contributions to both mathematics and science. An army contingent of 616 members is to march behind an army band of 32 members in a parade.

These questions are solved by expert master teachers who understand the exam pattern and are familiar with the CBSE curriculum.

Therefore, HCF of 867 and 255 is 51. Since 867 > 255, we apply the division lemma to 867 and 255 to obtain 90 = 2 x 45 + 0 Question number 1, 2, 3 are based on the prime factorisation method of LCM and HCF.

Maths can be a concern for many students as the subject tests understanding of formulas and concepts as well as problem-solving abilities. In Chapter 1 of 10th Maths, we observe that Euclid’s division algorithm has to do with divisibility of integers. \(\begin{array}{l}{\text {Case } 3 : \text { when } a=3 q+2} \\ {a^{3}=(3 q+2)^{3}} \\ {a^{3}=27 q^{3}+54 q^{2}+36 q+8} \\ {a^{3}=9\left(3 q^{3}+6 q^{2}+4 q\right)+8} \\ {a^{3}=9 m+8} \\ {\text { Where } m \text { is an integer such that } m=\left(3 q^{3}+6

Since the remainder is zero, the process stops. Carl Friedrich Gauss is often referred to as the ‘Prince of Mathematicians’ and is considered one of the three greatest mathematicians of all time, along with Archimedes and Newton.

Hence, it can be said that the square of any positive integer is either of

255 = 102 x 2+ 51 Step 2 If r = 0, the HCF is b .
