Question

If the product of HCF and LCM of two natural numbers is 378000 ,then which of the following can be their answer ?
(1)66
(2)130
(3)34
(4)20

Answer 1

20
Will be the answer because rest all goes in points and it has been asked to take out LCM and HCF product of the number so 20 is the answer

Answer 2

Answer:

Option 4 - 20

Step-by-step explanation:

Given : If the product of HCF and LCM of two natural numbers is 378000.

To find : Which of the following can be their answer?

Solution :

We know that,

$\text{Product of two number} =\text{HCF}\times \text{LCM}$

We have given that the product of HCF and LCM is one of the options and it completely divide the number 378000.

So, We divide the 378000  by the following numbers

1) $\frac{378000}{66}=5727.272$

2) $\frac{378000}{130}=2907.69$

3) $\frac{378000}{34}=11117.64$

4) $\frac{378000}{20}=6300$

Therefore, The number which completely divide the number is 20.

So, The required number is 20.
