4, 8, 12, 16, 20, 24, and just keep adding 4 until you get to 1000.
Numbers that are multiples of 4 are 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52, etc.
Any number using all ten digits once each, and ending in 0, 2, 4, 6 or 8 will do.
There are infinitely many of them and I am not stupid enough to try to list them.
Let's see. 4, 8, 12, 16, 20 Yup.
45, 63, 72, 81, 90
25 of them.
Yes.
Multiples of 2 are even numbers. All even numbers end in 0, 2, 4, 6 or 8.
0, 2, 4, 6, 8
Five multiples of three that use each digit from 0 to 9 only once are: 12, 30, 45, 69, and 87.
Yes, all whole numbers ending in 0 are multiples of 5.
It's false because there are other numbers ending 0 being multiples of 5.
That's not going to work. Multiples of 5 end in 5 or 0. With three numbers, one of those would have to repeat.
Yes. 0, 4, 8, 13572, 96
Multiples of 3: 123, 45, 6, 78, and 90 Multiples of 7: 7, 14, 28, 56, and 903 Primes: 5, 23, 41, 67, and 809
Tidy numbers are numbers that end with a 0 (10 and multiples of 10)
9
No No
Even numbers have to end with 2, 4, 6, 8, or 0. And multiples of 5 have to end in 5 or 0.
All multiples of 5 are numbers ending in either 5 or 0.
Any number using each of the digits once will be a multiple of 3: eg 1597864302
Yes.
There are 13 two-digit multiples of 7.
7, 42, 63, 98, 105
