Is all number divisible by 4 and 6 divisible by 24?
Yes.
If a number is divisible by 2 then its divisible by 4?
Oh, dude, that's not quite right. If a number is divisible by 2, it means it's even, but it doesn't necessarily mean it's divisible by 4. Like, 6 is divisible by 2 but not by 4. So, yeah, being divisible by 2 doesn't automatically mean it's divisible by 4.
Is 741 divisible by 3 4 5 6 9 10?
7 + 4 + 1 = 12 which is divisible by 3, so 741 is divisible by 3 741 is odd, all multiples of 4 are even, 741 is not divisible by 4 (Alternatively 4 x 2 + 1 x 1 = 9 which is not divisible by 4, so 741 not divisible by 4) All multiples of 5 end with 5 or 0, 741 ends with 1, so 741 not divisible by 5 To be divisible by 6, the number must be divisible by 2 (even) and divisible by 3.741 is odd, so not divisible by 2, so 741 is not divisible by 6 7 + 4 + 1 = 12 which is not divisible by 9, so 741 is not divisible by 9 All multiples of 10 end with 0, 741 ends with 1 so 741 is not divisible by 10 Summary: 741 is divisible by 3, but not by 4, 5, 6, 9 nor 10.
Is 642 divisible by 6?
Yes and it is 107
How can you tell that 642 is divisible by 3?
You can add up the digits, 6+4+2=12 and if that number is divisible by three, so it the original number. So 12 is certainly divisible by 3 so that means 642 is also.
Is 642 by divisible by 9?
No. 642 is not evenly divisible by nine.
Is 642 a prime number?
Just by looking at it, without trying any factors to see if they work, you can see-- 642 is even, i.e. divisible by 2, since it ends in '2'-- 642 is divisible by 3, since its digits add up to (6+4+2) = 12 which is divisible by 3.Just looking at 642, you already know of at least 2 factors that it has besides '1' and itself,so it can't be a prime number.
Is 642 divisible by 3?
Yes because 6+4+2 is divisible by three.The simple way to decide if any number is entirely divisible by three is to first discard any digit in the number that is divisible by three (3, 6, 9) then add any of the digits remaining together and if at any point you get something that is divisible by three you can disregard those digits. If at the end you have a remainder, the number is not evenly divisible by three. If there is no remainder the entire number is divisible by three.In your example 642, I threw away the 6 leaving 4 and 2 , added those = 6 which is divisible by three (actually I remembered that 42 was divisible by 6 so I knew right after I had taken away the first 6 that your number was divisible by 3.
