Answers
The number 117252090 is divisible by 2,3,5,9 and 10.
Step-by-step explanation:
number = 117252090
divisibilty by 2 : since the unit's digit is 0 it is divisible by 2
divisibilty by 3 : 1+1+7+2+5+2+0+9+0 = 27
and 27 is divisible by 3
therefore 117252090 is also divisible by 3
divisibilty by 4: If the last two digits of a whole number are divisible by 4, then the entire number is divisible by 4.
here, 90 is not divisible by 4
therefore, 117252090 is not divisible by 4.
divisibilty by 5: again the units place is 0 ,it is divisible by 5
divisibilty by 8:f the last three digits of a whole number are divisible by 8, then the entire number is divisible by 8
here, 090 is not divisible by 8
therefore it is not divisible by 8.
divisibilty by 9:sum of the digits is 27 and 27 is divisible by 9 therfore 117252090 is also divisible by 9.
divisibilty by 10: unit digit is 0, hence it is divisible by 10.
divisibilty by 11: sum of odd-numbered digits) 0+0+5+7+1 = 13
(sum of even-numbered digits) 9+2+2+1 =14
13-14 = -1 , it is not divisible by 11
hence ,
The number 117252090 is divisible by 2,3,5,9 and 10.
