1. LCM of 135 and 225 is 3.
2.According to Euclid’s Division Lemma if we have two positive integers a and b, then there exists unique integers q and rwhich satisfies the condition a = bq + rwhere 0 ≤ r ≤ b.
The basis of Euclidean division algorithm is Euclid’s division lemma. To calculate the Highest Common Factor (HCF) of two positive integers a and bwe use Euclid’s division algorithm. HCF is the largest number which exactly divides two or more positive integers. By exactly we mean that on dividing both the integers a and b the remainder is zero.
plz solve urself.
