Question

test check the divisibility by 2,3,4,5,6,7,8,9,10,11 by 2467098423 and 11560425987

Answer 1

they both are divisible by 2 and 3

Answer 2

divisiblity of 2 =
  <> 2467098423 
  if the number in ones place is even then  it is divisible 
 2467098423  3 is not an even number so it is not divisible by 2
   <> 11560425987
7 is not an even number so it is not divisible by 2
------------------------------------------------------------------------------------------------------
divisibility by 3 =
 <>2467098423
if the sum of the digits is divisible by 3 then it is divisible by 3
2+4+6+7+0+9+8+4+2+3 = 45 ,45/3 is divisible so the number is divisible 
<> 11560425987
1+1+5+6+0+4+2+5+9+8+7 = 48 ,48/3 is divisible so the number is divisible by 3
------------------------------------------------------------------------------------------------------
divisibility by 4 
 <> 2467098423
if the last two digits are divisible by 4 then the number is divisible.
2467098423    23/4 is not divisible therefore the number is not divisible
<> 11560425987
the last two digits are 87  87/4 is not divisible so the number is not divisible.
------------------------------------------------------------------------------------------------------
divisibility by 5 =
<>2467098423 
if the numbers last digit have 0,5 numbers then it is divisible by 5
2467098423  is not divisible.
<>11560425987
it is not divisible 
------------------------------------------------------------------------------------------------------
divisibility rule for 6 =
if the number is divisible by 2 and 3 then it is divisible by 6
<> 2467098423
divisibility 2 =no
divisibility 3= yes
so the number is not divisible
<>11560425987
divisibility 2 = no
divisibility 3 =yes
so the number is not divisible.
-----------------------------------------------------------------------------------------------------
divisibillity by 7 =
take the last digit double it subract it from rest of the number
<>2467098423
3*2 =6 
246709842 - 3 = 246709839
<>11560425987 
7*2 =14
11560425987 -14 =11560425973
------------------------------------------------------------------------------------------------------
divisibilty by 8 =
if the last two digits are divisible by 8 then the number is divisible
<>2467098423
23 /8 is not divisible so the number is not divisible
<> 11560425987
87/8 is not divisible so the number is not divisible
-----------------------------------------------------------------------------------------------------
divisibility of 9 =
<> 2467098423
 if the sum of the numbers is divisible by 9
2+4+6+7+0+9+8+4+2+3=45
45/9 is not divisible so the number is not divisible
<> 11560425987
1+1+5+6+0+4+2+5+9+8+7=48
48/9  is not divisible so the number is not divisible
------------------------------------------------------------------------------------------------------
divisibility of 10 =
<> 2467098423
if the last digit of the number is  0 then the number is divisible
the number is not divisible 
<> 11560425987
the number is not divisible
------------------------------------------------------------------------------------------------------
divisibility by 11=
sum of the digits divided by 11
<> 2467098423
2+4+6+7+0+9+8+2+3= 45 /11 is not divisible 
<> 11560425987
1+1+5+6+0+4+2+5+9+8+7= 48/11 is not divisible
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
