Question

The HCF of two numbers is 123 and their LCM is 9471 if one of the number is 861 find the other​

Answer 1

The HCF and LCM of two numbers is 123 and 9471 respectively.

One of the number is 861.

We have to find, The other number.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━

☯ Let the another number be b.

Here,

• HCF = 123

• LCM = 9471

• one number = 861

We know that,

★ LCM × HCF = Product of two number

Putting values,

➯ 9471 × 123 = 861 × b

➯ 1164933 = 861 × b

➯ b = 1353

∴ The other number is 1353.

★ More to know:

• HCF (Highest common factor) = Highest factor present between two numbers.

• LCM (least common multiple) = Least number which is exactly divisible by two or more numbers.

Answer 2

Question :-

the HCF of two numbers is 123 and their LCM is 9471 if one number is 861 find the other ?

Solution :-

Given ;

• the LCM and HCF of two number is 9471 and 123
• one number is 861 .

What we have to find here ?

=> we are going to find the other number .

So,

Let the other number be "x" .

According to the question ,

To find the value of the other no. formula to be used is ;

LCM × HCF = PRODUCT OF TWO NUMBERS .

Now,

substituting the values in the place ;

9471×123=186× x

=> 1164933 = 186 ×x

=> x=1164933/186

=> x=1353

Hence , the other number is 1353 .
