DIVISIBILITY BY SEVENTEEN : Negative osculator for 17 is 5 (see note). The working for this is the same as in the case of 7.Ex 1 : Check the divisibility of 1904 by 17. Soln : 190 4 : 190  5x4 = 170 Since 170 is divisible by 17, the given number is also divisible by 17. Note : Students are suggested not to go upto the last calculation. Whenever yoti find the number divisible by the given number on right side of your calculation stop further calculation and conclude the result. Ex 2 : 957508 95750 8 : 95750 5x8 = 95710 9571 0 : 9571 5x0 =9571 957 1 : 957  5x1 = 952 95 2 : 95  5x2 = 85 Since 85 is divisible by 17, the given number is divisible by 17. Ex 3: 8971563 897156 3 : 897156 5x3 = 897141 89714 1 : 89714  5x1 = 89709 8970 9 : 8970  5x9 = 8925 892 5 : 892  5x5 = 867 86 7 : 86  5x7 = 51 Since 51 is divisible by 17, the given number is also divisible by 17.
