Find the number of zeroes at the end of 25 5
WebNow the number of zeros in the non-factorial part i.e. 10 100 = 100 And the number of zeroes in the factorial part i.e. 100! = 100/5 + 100/25 = 20 + 4 = 24 So the total umber of zeros in the product = Zeros in non-factorial part + zeros in factorial part i.e. 100 + 24 = 124 (option ‘C’) QUERY 4 Find the number of digits in 244 × 512 A) 14 B) 12 WebFeb 10, 2024 · Each number divisible by 5 will contribute 1 factor of 5. There are 55/5 = 11 such numbers. Each number divisible by 25 will contribute an additional factor of 5. There are floor(55/25) = 2 of those. So, there are a total of 11+2 = 13 factors of 5 in the number 55!. This means there are 13 trailing zeros in the number 55!.

WebFor smallish numbers, you could try getting a multiple of 6 = 1 + 5 close to your number, find the number of zeroes for 25 / 6 times that and try to revise your estimate. For example for 156 = 6 ∗ 26. So try 26 ∗ 5 ∗ 5 = 650. 650! has 26 ∗ 5 + 26 + 5 + 1 = 162 zeroes. Since you overshot by 6, try a smaller multiple of 6. WebMay 17, 2016 · In 900! we need to consider how many 2's and 5's there will be. Clearly there will be more 2's than 5's so the limiting factor for creating zeros at the end will be 5's. In …

WebSep 4, 2024 · Trailing zeroes are as the name points zeroes in the end of the number. So 10 has 1 trailing zero. And because this is a question regarding base10 numbers, this is how you can represent any number with trailing zero - number0 = number x 10. And because 10 is actually 2 x 5 you need 2s and 5s. One 2 is enough to 'turn' all fives into zeroes.
WebMar 2, 2024 · is 25. Therefore, option C is the correct answer. Note: To find the exact number of zeros which are present at the end of a factorial, we should know how many times the given number will be divisible by 10.
