All multiples of 20 are.
148 is divisible by 4, not by 5
a number that is divisible by 3 and 5 but not by 4= 15
No. divisible by 3 4 5 is 60
no 3135 is divisible by 5 rather 4
There are infinitely many numbers divisible by 5 and 4. 680 is one of them.
650130 is not divisible by 4, but it is divisible by 2, 3, 5, 6, and 10
It's trivially obvious that it's NOT divisible by 5, since doesn't end in 5 or 0. That means it's also not divisible by 10. (Not all numbers that are divisible by 5 are divisible by 10, but every number that is divisible by 10 is also divisible by 5.) 1+0+4+4 = 9, so it is divisible by 3 (and by 9). It ends with a 4, so it's divisible by 2. The last two digits are 44, which is divisible by 4, so the entire number is divisible by 4. Being divisible by 2 and 3 means it's also divisible by 6.
740 is divisible by both 4 and 5.
20
It is divisible by 2 & 3. It is not divisible by 5, 9 & 10. 534 is even → divisible by 2 5 + 3 + 4 = 12 → divisible by 3 534 does not end in 0 or 5 → not divisible by 5 5 + 3 + 4 = 12 → not divisible by 9 534 does not end in 0 → not divisible by 10
4, yes.5, no.
