Euclid division lemma
highIf one integer a is divided by another positive integer b, we can write a = bq + r, where q is the quotient and r is the remainder, with 0 <= r < b.
Always write the condition 0 <= r < b after the division form. Many CBSE answers expect both the equation and the remainder condition.
Iterative division for HCF
highIterative division for HCF is a step-by-step method where the larger number is divided by the smaller number, then the divisor and remainder are used again until the remainder becomes 0. The last non-zero remainder is the HCF.
Write each division clearly and stop only when the remainder becomes 0. The last non-zero remainder is the answer.
