@Jakobian i used your trailing zero identity but still left with a very large number which is something around 2^73
Jun 23 05:48
sum of digits in 100!
Jun 23 05:48
can u give me trivial way of calculating digits of of 100!
Jun 23 05:47
like if i removed the zeros we are still left with large number how do i see repetition of the numbers like ,2,4,5,7,9
Jun 23 05:46
@Jakobian what about the sum of the digits?

i wish to see learn how do compute this number without manually doing this like zeros and prime factors
Jun 22 09:50
like i came upto trailing zero which is 24 honestly do not know how we get even that gif [n/5]+[n/25]....
Jun 22 09:49
how do we calculate the sum of digits of 100!
Jun 22 09:49

Help me in this I do not know where I goes wrong :

Question:

Consider the following sequence of numbers: 85, 87, 89, 91, 95, 96. We will explore the behavior of the last two digits when these numbers are multiplied.

1. Step 1: Multiply 95 and 96
Start by multiplying 95 and 96. Observe the last two digits of the result. The last two digits of the product are 20 (since 95 × 96 = 9120).


2. Step 2: Multiply the Result by 87
Now, multiply the product from Step 1 (which ends in 20) by 87. Notice how the units and tens digits of the product evolve. The units digit of the product will be

Sir does minus explain that we are moving in counter clockwise direction
Oct 5, 2024 09:28
?
Oct 5, 2024 09:28
87 multiply by 89 multiply 90 multiply 91 multiply 93 multiply by 97 multiply by 98 multiply by 99 divided by 100 will give remainder
Oct 5, 2024 09:27
Sir i have similar question related to it
Oct 5, 2024 09:25
Last time when we had a talk u were complaining about back pain
Oct 5, 2024 09:24
@PM2Ring by the way how is ur back now?
Oct 5, 2024 09:24
Thanks sir
Oct 5, 2024 09:19
Oh ok
Oct 5, 2024 09:16
It is 8 after 3 squarings
Oct 5, 2024 09:15
Ok
Oct 5, 2024 09:13
Yes
Oct 5, 2024 09:11
Cycle repeat after 7 so after 64 cycle we would be at 2
Oct 5, 2024 09:11
(322 mod 10) ^128
Oct 5, 2024 09:09
2
Oct 5, 2024 09:06
@PM2Ring answer is 8?
Oct 5, 2024 08:51
@RyderisnotRude. No
Oct 5, 2024 08:51
But since it is not the multiple of 2 how do I approach it
Oct 5, 2024 08:51
And cycle of 2^n repeat itself after 4 so if it would have been 256 I could have easily says last digit would be 2
Oct 5, 2024 08:48
And since the last digit is 2 it should be 256
Oct 5, 2024 08:47
I looked for the nearest possible square to 322
