3 x17 is 51 51 is not a prime number it is composite. use this rule : You wil know a number is divisible by 3 if you add up the digits. if the sum is a multiple of 3 then that number is divisible by 3. i.e.: 51 5+1 =6 6 is divisible by 3 so 51 is divisible by 3. 51/3= 17
1, as are all numbers. oh, and 17.
All but 56789 are.
1, 3, 7, 17, 21, 51, 119, 357
3, 5, 15, 17, 25, 51, 75, 85, 255, 425.
51 and 54 are divisible by 3.
No, but it is divisible by 1, 3, 17, 51.
No. 51 is not evenly divisible by four.
51 is.
9/51=0.176470588
1, 3, 17, 51
5 + 1 = 6 which is divisible by 3, so 51 is divisible by 3. [3 x 17 = 51]
47 is a prime number and is divisible by 1 and 47 only. 51 is divisible by 1, 3, 17, 51.
No. 51 is not evenly divisible by 12.
Yes. 51/3 = 17. To find out if a number is divisible by three simply add up the values of the digits and see if that number is divisible by three. 51 -- 5 + 1 = 6 -- 6 is divisible by 3 so 51 is as well.
The multiples of 51 (which are infinite) are all divisible by 51 , including these: 102, 153, 204, 255, 306, 357, 408, 459, 510 . . .
Yes; 51 divided by 3 is 17.
