Question

Check the divisibility of the following by 4 and 8 :
(a) 592 (b) 726356 (c) 5600 (d) 8000
(e) 12156 (f) 21084 (g) 17800 (h) 96128
(i) 4678 (j) 99060​

Answer 1

Answer:

Step-by-step explanation:

to check the divisibility by 4 just take tens and unit place number and divide by 4, if the remainder is zero means the number is divisible by 4 and if the remainder is not zero then the number is not divisible by 4.

to check the divisibility by 8 just take hundred, tens and unit place number and divide by 8, if the remainder is zero means the number is divisible by 8 and if the remainder is not zero then the number is not divisible by 8.

options divisible by 4- a,b,c,d,e,f,g,h,j

options divisible by 8- a,c,d,g,h

Step-by-step explanation:

to check divisibility of a number by 4 and 8, the following should be followed.

• it's last 2 numbers should be divisible by 4 to be divisible 4.
• it's last 3 numbers should be divisible by 8 to be divisible by 8.
• if a number is divisible by 8, it is definitely divisible by 4.

a) 8. 592 are the last 3 numbers of 592. and 592 is divisible by 8

4. 92 are the last 2 digits of 592. 92 is divisible by 4, so 592 is divisible by 4.

b) 356 is not divisible by 8, so it is not a multiple of 8.

56 is divisible by 4, so it is a multiple of 4.

c) 600 is not divisible by 8, so the number is not a multiple of 8.

00 is a multiple of 4, so the number is divisible by 4.

d)000 is divisible by 8, so it is a multiple of 8.

00 is a multiple of 4, so the number is divisible by 4.

e) 156 is not divisible by 8, so 12156 is also divisible by 8.

56 is a multiple of 4, so the number is divisible by 4.

f) 084 is not divisible by 8, so the number is not a multiple of 8.

84 is divisible by 4, so the number is a multiple f 4.

g) 800 is divisible by 8, so this number is a multiple of 8.

f 00 is divisible by 4, so the number is also a multiple of 4.

h) 128 is not divisible by 8, so the number is not divisible by 8.

28 is a multiple of 4, so the number is divisible by 4.

i) 678 is not divisible by 8, so the number is also not divisible by 8.

78 is not a multiple of 4, so the number is not a multiple of 4 either.

j) 060 is not a multiple of 8, so the number is not divisible by 8.

60 is a multiple of 4, so this number is divisible by 4.
