how to find the multiple of 2 and 3 in agiven range?

Answer 1

Hi Mate !!


• To find the multiple of 2 in given range :-

° If the number ends with an even number than the number is exactly divisible by 2.

For eg. :- 32456 ends with 6
and 6 is even number
hence the number 32456 will be exactly divisible by 2.

• To find the number divisible by 3 Or the multiple of 3 :-

° Add the digits of given number and if the sum of the digit is 3 , 6 , 9 .... any multiple of 3 then the number will be exactly divisible by 3

For eg. :- 32456 :- 3 + 2 + 4 + 5 + 6 = 20
Since , 20 is not the multiple of 3 hence the number is not divisible by 3.

324 :- 3 + 2 + 4 = 9
Since , 9 is the factor of 3
hence the number 324 will be exactly divisible by 3 !!

Answer 2

for multiple of 2 general term is 2n

where n = 1,2,3...............n ;

for multiple of 3 general term is 3n

where n = 1,2,3,.........n ;

for multiple of 2 and 3 both general term is 6n

where n = 1,2,3,........n
