Question

Using prime factorization, find the HCF and LCM of:
$17,23,29$

Answer 1

$17={17}^1={17}^1\times {23}^0\times {29}^0$

$23={23}^1={17}^0\times {23}^1\times {29}^0$

$29={29}^1={17}^0\times {23}^0\times {29}^1$

From the above

$HCF={17}^0\times {23}^0\times {29}^0=1$

$LCM={17}^1\times {23}^1\times {29}^1=11,339$
