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
All but 56789 are.
1, 3, 7, 17, 21, 51, 119, 357
three and 17
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.
5 + 1 = 6 which is divisible by 3, so 51 is divisible by 3. [3 x 17 = 51]
1, 3, 17, 51
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.
yup
