Answer:
Step-by-step explanation:
To find the other number given the LCM and HCF of two numbers and one of the numbers, we can use the relationship between the LCM, HCF, and the product of the two numbers. The relationship is:
\[
\text{LCM}(a, b) \times \text{HCF}(a, b) = a \times b
\]
Given:
- LCM = 690
- HCF = 175
- One number \(a = 230\)
We need to find the other number \(b\).
Using the relationship, we have:
\[
\text{LCM} \times \text{HCF} = a \times b
\]
Substitute the known values:
\[
690 \times 175 = 230 \times b
\]
Solve for \(b\):
\[
b = \frac{690 \times 175}{230}
\]
Now, calculate the value:
\[
690 \times 175 = 120750
\]
\[
b = \frac{120750}{230} = 525
\]
So, the other number is \(525\).
Answer:
Step-by-step explanation:
HCF = 175
LCM = 690
ONE NUMBER = 230
OTHER NUMBER = ?
WE KNOW THAT,
LCM * HCF = 1ST NO. * 2ND NO.
690 * 175 = 230 * 2ND NO.
2ND NO. = 690*175/230
2ND NO. = 525
