Question

give that HCF(48,57)=4 find their LCM
​

Answer 1

Answer:

We know

HCF × LCM = product of numbers

=> 4 × LCM = 48 * 57

=> LCM = 48 × 57/4

$= \frac{48 \times 57}{4} \\ = 12 \times 57 \\ = 684$

so, their LCM is 684...

Answer 2

Answer:

$hcf \times lcm = product \: of \: numbers$

$4 \times lcm = 48 \times 57$

$lcm = \dfrac{48 \times 57}{4}$

$lcm = 12 \times 57$

$lcm = 684$
