How large is 52 factorial?

52! is approximately 8.0658e67. For an exact representation, view a factorial table or try a "new-school" calculator, one that understands long integers. A billion years currently equals 3.155692608e16 seconds; however, the addition of leap seconds due to the deceleration of Earth's orbit introduces some variation.

What is the 52 factorial deck of cards?

The number of possible ways to order a pack of 52 cards is '52! ' (“52 factorial”) which means multiplying 52 by 51 by 50… all the way down to 1. The number you get at the end is 8×10^67 (8 with 67 '0's after it), essentially meaning that a randomly shuffled deck has never been seen before and will never be seen again.

How many orderings are there for a deck of 52 cards if all the cards of the same suit are together?

ways to order the cards. Thus the total number of ways ordering a deck of cards with each suits together is 4!

How long would it take to shuffle every order in a pack of cards?

Try 300 quintillion years. To find out how many individual orders you can get using all 52 cards, we need to work out 52! – remember, that's 52 factorial, not 52 in an excited voice. That comes to about 8 × 10⁶⁷, or to put it in words, 80 thousand vigintillion different shuffles.

Combinations of 52 cards (52 factorial)

Are there infinite ways to shuffle cards?

No one has or likely ever will hold the exact same arrangement of 52 cards as you did during that game. It seems unbelievable, but there are somewhere in the range of 8x10⁶⁷ ways to sort a deck of cards. That's an 8 followed by 67 zeros.

Is every card shuffle unique?

Each thoroughly shuffled deck of cards is, in all likelihood, unique, meaning it has never existed before and will never exist again.

What are the odds of shuffling cards in the same order?

If you truly randomise the deck, the chances of the cards ending up in perfect order - spades, then hearts, diamonds and clubs - are around 1 in 10 to the power 68 (or 1 followed by 68 zeros). That's a huge number, roughly equal to the number of atoms in our galaxy.

Why is 0 factorial 1?

Factorial of a number in mathematics is the product of all the positive numbers less than or equal to a number. But there are no positive values less than zero so the data set cannot be arranged which counts as the possible combination of how data can be arranged (it cannot). Thus, 0! = 1.

What is the largest factorial ever calculated?

The last factorial is 170! “Did you know? The number 170 is the highest possible number you can calculate a factorial for? Any higher than 170, and the mathematical answer is infinity.” - visualfractions.com/calculator/fac…

What is a fun fact about Factorials?
