Question

plz answer this problem..........

Answer 1

Here is the solution :

We know that,
A number is known as a Composting number if it has more than 2 factors,

Here,
The given Number is,
7 x 11 x 13 + 13,

Now taking 13 common,
=> 13(7*11+1),

Here we can observe that this number has more than 2 factors they are 1, 13, and (7*11+1),

So this is a Composite Number',

Another number = 7*6*5*4*3*2*1 + 5,
Taking 5 common here,
=> 5(7*6*4*3*2*1 + 1)

Here also we can see that there are more than two factors,

They are,
1,5, and (7*6*4*3*2*1 +1)

So,
Therefore : The two given numbers are Composite Numbers !

Hope you understand, Have a Great day !
