No.
If the sum of (the hundreds digit times 4) plus (the tens digit times 2) plus (the ones digit [times 1]) is divisible by 8, then so is the original number:
2 x 4 + 1 x 2 + 8 x 1 = 18 which is not divisible by 8, so 218 is not divisible by 8.
218 is NOT divisible by 5 so the question, as stated, makes no sense.
no, 218 divided by 9 is 24.222
No.
No.
1, 2, 4, 8, 16, 109, 218, 436, 872, 1744.
1, 2, 4, 8, 16, 109, 218, 436, 872, 1744.
All multiples of 218 (which are infinite) including 218, 436, 654, 872, 1090 . . .
The product of the prime factors of 218 is 218. The prime factors of 218 are 2 and 109, making their product 2 x 109 = 218! I wouldn't expect it to be otherwise: the product of the prime factors of a number equal the number.
Yes, any number is divisible by any other number
345 and 218
No. 436 is only divisible by: 1, 2, 4, 109, 218, 436.
As an even number greater than 2, 218 is divisible by 2 and therefore composite. Its positive integer factors are: 1, 2, 109, 218
