Question

the HCF and LCM of two numbers are 12 and 5040 , respectively . if one of the numbers is 144 , find the other number?​

Answer 1

❍ Let the other required number be x respectively.

⠀

$\underline{\bf{\dag} \:\mathfrak{As\;we\;know\: that\: :}}$

$\bf{\star}\;\boxed{\textsf{\textbf{\pink{Product\;of\;two\; Numbers\;=\;LCM \times \: HCF}}}}⋆$

Therefore,

⠀⠀⠀

$\begin{gathered}:\implies\sf x \times 144 = 12 \times 5040\\\\\\:\implies\sf x \times 144 = 60480 \\\\\\:\implies\sf x = \cancel\dfrac{60480}{144} \\\\\\:\implies{\underline{\boxed{\pink{\frak{x = 420}}}}}\;\bigstar\end{gathered}$

$\therefore{\underline{\textsf{Hence, the other required number is {\textbf{420.}}}}}$

Answer 2

Answer:

$420$

Explanation:

144 × X = 12 × 5040

X = (12 × 5040)/144

X = 420
