Question

What is the last digit of the product of all the numbers between 11 and 29?

Answer 1

we can conclude that the last digit of the product of all the numbers between 11 and 29 is 0.

What is the last digit of the product of all the numbers between 11 and 29?

Here we want to find the last digit of the product between all the whole numbers larger than 11 and smaller than 29.

Then we have the product:

P = 12*13*14*15*16*17*18*19*20*21*22*23*24*25*26*27*28

Now, notice that there is a 20 there.

Any number times 20 will end with a zero, then:

P = 20*(12*13*14*15*16*17*18*19*21*22*23*24*25*26*27*28)

Only with that, we can conclude that the last digit of the product of all the numbers between 11 and 29 is 0.
