If the last digit doubled subtracted from the rest is a multiple of 7, the whole number is divisible by 7.
Example: 686
68 - 12 = 56
56 is divisible by 7.
686 is divisible by 7.
973 is divisible by: 1, 7, 139, 973.
No, it is not.
Double the last digit, subtract it from the rest. If the result is divisible by 7, the whole number is divisible by 7.
If you double the last digit and subtract it from the rest of the number and the answer is zero or divisible by 7, then the whole number is divisible by 7.
They are both divisible by: 14, 7, 2 and 1
7 is not divisible by 104 and 104 is not divisible by 7.
Not only is 119 divisible by 7 but it is evenly divisible by 7.
No it is not divisible by 7
No, but 504 is divisible by 7.
23 is not divisible by 7.
no 7 is divisible by 14. :)
No, 604 can't be divisible by 7.
all numbers are divisible by 7.
No, 7 is a natural number divisible by 7 and not 14 for example. In fact every odd multiple of 7 (i.e. 7 times 1,3,5,7,...) is divisible by 7 and not 14.
No, 364 is not divisible by 7. When you divide 364 by 7, you get a remainder of 0. Therefore, 364 is divisible by 7.
No, 10032 is not evenly divisible by 7.
Wishful thinking? 7 is NOT divisible by 2.
