Explanation:
143 = 11 × 13. So highest power of 13 should be considered in 125!.

Highest power of 11 in 125! is 12 but highest power of 13 is only 9. That means, 125!=1112×139×....1112×139×....
So only nine 13's are available. So we can form only nine 143's in 125!. So maximum power of 143 is 9.

to know how many 0 we hve to find number of 2s and 5S by factorization, by factorizing a number it has many n of 2s but only by knowing number of 5s we can tell how many zeros are there


in the same way this ques has many 11*13 =143
to calculate how many 143s are present simply calculate 13 s
it has 9 13s
