Q. How many zeroes are there are at the end of the product 125×16×92×15×12×75× 24 ?

Answer :

To find out how many zeros at the end of the product 125 $\times$ 16 $\times$ 92 $\times$ 15 $\times$ 12 $\times$ 75 $\times$ 24

We know the product of what numbers when multiplied ends in a zero:

1 ) When one of the things being multiplied ends in zero itself.
2 ) A number ending in 5 multiplied by an even number.
3 )  25, 50 and 75 when multiplied by some of the small numbers available eg (4, 2 and 6) generate an extra zero.

Here we find values of 125 $\times$ 16  =  2000
And
92 $\times$ 15  =  1380

And
12 $\times$ 75  = 900

So we have 

2000 $\times$  1380  $\times$  900  $\times$  24  , we can write it as :

2 $\times$  1000 $\times$  138 $\times$  10 $\times$  9 $\times$  100 $\times$  24  , So

2 $\times$  138 $\times$  9 $\times$  24 $\times$  1000000 

So product of these numbers gives 6 zeros at the end of the product value .

So,

Our number of zeros  =  6  at the end of the product .  ( Ans )
