Question

q.१) find the HCF of the following numbers.
1) 45,30
​

Answer 1

We know that ,

First we find prime factorization of 45 and 30.

$\large \implies \:45 = 3 \times 3 \times5 \\ \\ \large \implies \: 30 = 2 \times 3 \times 5$

$\bf\large \rightarrow \: Common \: \: Factor = 3 × 5$

$\bf \LARGE \: HCF \: = 15$
