Divisibility Test for 5 Video Lecture - Class 8

hi so in this video we are going to
discuss the divisibility rules of five I
know it's very easy and the rule is also
very easy and it's very easy to identify
if a number is divisible by five or not
so any number which has zero or five at
its unit's place is divisible by five so
suppose if i write a number ten it is
divisible by five five to the ten and
but if I write 13 as per this rule this
will not be divisible by five right
let's divide it thirteen divided divided
by five five to the ten if you subtract
you are going to get 3 as remainder
right so 13 is not divisible by five
right and if I write something like five
thousand four hundred and thirty five
this also has five at units place so it
will be divisible by five and if you
want we can divide and check it so let's
do that so five four three five when I
divide it by five five one so five
remainder is zero let's note down the
four or is not divisible by five so I
will put a zero and note down the next
number
so three five eights are 40 and if I
subtract and get three and let me note
down five again it's five five sevens
are thirty-five no remainder right so it
is divisible by five so the logic behind
this divisibility rule is if I write
down the table of five it is five months
a five five to the ten by three is
fifteen my foes are twenty five fives
are twenty five five six or 35 seven to
thirty five five eights of forty five
nines at 45 and
50c all these numbers have either 5 or 0
at units place right so any number which
is coming in the table of 5 will have
either 0 at the unit place or it will
have 5 at the unit's place so I think
this divisibility rule is very simple
and all of you are very smart to
understand it but watch few more
divisibility rules I am explaining the
divisibility rule of seven eleven
thirteen nine and six also so watch
videos on divisibility at maths much
