Which of the following number is not divisible by 2, 3 and 6 is

1) 800552 2) 312792 3) 972132 4) 391002​

Answer 1

Answer:

1)800552

Step-by-step explanation:

a number is divisible by 2 if last digit (0,2,4,6,8)

a number is divisible by 3 if sum of digits is divisible by 3

a number is divisible by 6 if it is divisible by both 2&3

1) 800552- last digit 2 so it is divisible by 2

sum of digits =8+0+0+5+5+2=20. which is not divisible by 3

so it's not divisible by 6 also
