No.A number a is divisible by another number b, if and only if the fraction a/b is equivalent to a whole number. And as you know, 1/2 = 0.5, which is not a whole number, hence is 1 not divisible by 2.The only number 1 is divisible by, is 1 itself. All numbers are divisible by 1.
If a number is divisible by both 2 and 3, it is also divisible by 6. This is because 6 is the least common multiple of 2 and 3. Therefore, any number that meets the criteria of being divisible by both 2 and 3 will also be divisible by 6.
30 is divisible by, and is the least common multiple of, 2, 3, and 5.

No it is not. A prime number is only divisible by 1 and itself, whereas 784 is at least divisible by the number 2 as well. 784/2=392
Yes. Every number is divisible by itself or 1.
620 is not prime. 620 is divisible by at least 2. By definition prime numbers are only divisible by 1 and themselves.
