Question

If the LCM and 861 and 1353 is 9471
find their HCF​

Answer 1

LCM = 9471

HCF = ?

we know that,

= Products of number = Product of LCM and HCF

= 861 × 1353 = 9471 × HCF

= HCF = (861 × 1353) / 9471

= 123

here is your answer

hope it will help you

Answer 2

$</p><p>{\huge{\red{\boxed{\mathbb{\blue{\underline{\blue{A}{\red{N}{\pink{S}{\orange{W}{\red{E}{\purple{R} }}}}}}}}}}}}$

LCM $\times$ HCF = Lroduct of the two numbers.

LCM = 861

Two No. are = 1353 and 9471

So,

$861 \times$ HCF = $1353 \times 9471 \\ => HCF = \frac {1353 \times 9471}{861} \\ => HCF = 14833$
