Question

the hcf and lcm of two numbers are 14 and 490.if one of the number is 70 find the other number​

Answer 1

$\bold{ \frac{HCF \times LCM}{one \: number} }$

$\bold{ \frac{14 \times 490}{70} }$

$\bold{ \cancel\frac{6860}{70} }$

$\bold{98}$

So, the other number is 98

Answer 2

Answer:

$\blue{\mathfrak{\underline{\large{Given}}}:} \\ LCM = 490 \\ HCF = 14 \\ a = 70\\ \blue{\mathfrak{\underline{\large{To \: find }}}:} \\ other \: number = b \\ \blue{\mathfrak{\underline{\large{Finding}}}:} \\ LCM \times HCF = a \times b \\b = \frac{LCM \times HCF}{a} \\ b = \frac{490 \times 14}{70} \\ \boxed{b = 98} \\ \\\red{\mathfrak{ \large{\underline{{Hope \: It \: Helps \: You}}}}} \\ \blue{\mathfrak{ \large{\underline{{Mark \: Me \: Brainliest}}}}}$
