Question

Which of the numbers 4,6 and 9 divide exactly 51420

Answer 1

Answer:

4 and 6

Step-by-step explanation:

For a number to be divisible by 4 the last 2 digs of the number have to be divisible by 4.

last 2 digits of 51420 are 20

and 4x5=20

so 51420 is divisible by 4

For a number to be divisible by 6 it has to be divisible by 3 and 2 both

it is clearly divisible by 2

for a number to be divisible by 3 the sum of digits has to be divisible by 3

5+1+4+2+0=12

12 is divisible by 3

so 51420 is divisible by 6

for a  number to be divisible by 9

the sum of the digits has to be divisible by 9

as 5+1+4+2+0=12 which is not divisible by 9

the number is not divisible by 9

so 51420 is divisible by 4 and 6 but not 9
