2468 is not a prime number because it has more than twofactors.Points to remember!1-Every number except 0 is divisible by itself.2-Every number is divisible by 1.3-It means every number except 0 and 1 has minimum two factors.Therefore, 2468 has factors: 1 and 2468.In order to show that given number is not prime there is no need to find all the factors we just have to show that it has more than two factors.2468 is also divisible by 2, which means that 2 is also a factor of 2468(more than two factors).Therefore, 2468 is not a prime number.
Anything that isn't 1, 2, 4, 617, 1234, 2468
Because every even number of fives is a multiple of ten, and ends in zero. 5 x 2 = 10
By 2 but not by 3. 2690 is a multiple of 2 because it ends in 0 but it isn't a multiple of 3 because 2 + 6 + 9 = 17 and 17 isn't a multiple of 3
600 divisble by:2 it is even3 the sum of digits is a multiple of 3 (6 + 0 + 0 = 6)4 the last two digits is a multiple of 45 it ends with 0 or 56 it is divisible by 2 and 38 the last three digits is multiple of 810 it is ends with 0

2, 4, 617, 1234 are the factors of 2468
1, 2, 4, 617, 1234, 2468 2 and 617 are prime.

A number that ends in 3 can't be a multiple of 4 because the 4 times table goes in a pattern, (e.g 4, 8, 12, 16, 20, 24.) If the number ends in either 0 2 4 6 8 then it couldbe a possible multiple of 4. It always ends in an even number. 3 is not an even number so it is not going to be the last number of a multiple of 4.
2 and 617
2 x 2 x 617
0 and 5. Every multiple of 5 ends in one of those 2 digits. 5 times any even number ends in 0; 5 times an odd number ends in 5.
Oh, dude, 1234 times 2 is like, 2468. It's like doubling your money, but with numbers. So, if you had 1234 friends, and each one gave you 2 bucks, you'd be rolling in 2468 dollars. Math can be fun, right?
