### Divisibility Rules for 6

• The divisibility rule for 6 is as follows:

• If the number can be divided by BOTH 2 and 3

• Ex. Determine whether the number 876 453 is divisible by 6

• Solution:

• the last digit is not even, so the number is not divisible by 2.

• 8+7+6+4+5+3=33

• 3+3=6

• 6/2=3

• Since 3 is a factor of 33, the number is divisible by 3

• Therefore, 6 is not a factor of 876 453 because 2 is not a factor

• Determine whether the number 839 729 384 192 is divisible by 6.

• Solution:

• 8+3+9+7+2+9+3+8+4+1+9+2= 65

• 6+5=11

• Therefore, 6 is not a factor of 839 729 384 192 because 3 is not a factor

Example#2

• Determine whether the number 45 672 978 is divisible by 6

• Solution:

• 4+5+6+7+2+9+7+8=48

• 4+8= 12

• 12/3=4

• Therefore, 6 is a factor of 45 672 978 because 2 and 3 are factors.

• Explain whether the number 186 is divisible by 6.

• 1+8+6= 15

• 1+5=6

• 6/3=2

• Yes it is.

• Explain whether the number 283 945 is divisible by 6.

• 2+8+3+9+4+5= 31

• 3+1=4

• 4/3

• No
