There is no such number. A Prime number cannot be divisible by 4. If the product of the digits is less than 5 and there are only two digits, the possible digits could be {0, 1}, {0, 2}, {0, 3}, {0, 4}, {1, 1}, {1, 2}, {1, 3}, {1, 4}, or {2, 2}. Thus, the possible numbers are 10, 20, 30, 40, 11, 12, 21, 13, 31, 14, 41, or 22. The prime numbers among these numbers are 11, 31, and 41. The numbers divisible by 4 among these numbers are 20, 40, and 12.

Is 1 trillion 17 a prime number?
Since the sum of the digits is divisible by 3, the original number is also divisible by 3.Since the sum of the digits is divisible by 3, the original number is also divisible by 3.Since the sum of the digits is divisible by 3, the original number is also divisible by 3.Since the sum of the digits is divisible by 3, the original number is also divisible by 3.
If a number is divisible by co prime numbers then it is also divisible by their?
It is divisible by their factors. It is also divisible by their product.
Find 5 four digit numbers such that the product of the digits of each four digit prime number are also prime?
You had me until "product." The product of 4 digits can't be prime.
Can you make a prime number from the numbers 1 0 8?
A prime number is only divisible by 1 and itself. If all three digits have to be used then any number formed from them is divisible by 9 as the sum of the digits = 9. Thus no prime number can be formed. If only two of the three digits are used then it cannot end in 0 or 8 as it would be divisible by 2. This only leaves 81 where the digits again total 9 and thus is divisible by 9. None of the single digits 0,1,8 are prime. 8 is an even number. 1 is classed as unity, 0 is zero.
Explain why 21 is not a prime number?
21 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 3. (You can check this by adding the digits of the number: 2 + 1 = 3. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Therefore, 21 is a composite number.

Is 345456543 a prime number?
No, this number is divisible by 3 and hence is not a prime number. You can tell that fast by adding the individual digits. If that sum is itself divisible by 3, as this one is, then the number itself is divisible by 3.
If a number is divisible by co prime numbers then it is also divisible by their?
It is divisible by their factors. It is also divisible by their product.
Is 111111 a prime number?
No. It is divisible by 3, as you will see if you add up the digits.
Is 81 prime number?
81 has factors other than 1 and itself, so it is not a prime number. For example, it is divisible by 3. (You can check this by adding the digits of the number: 8 + 1 = 9. If the sum of the digits is divisible by 3, the number is also divisible by 3.) Therefore, 81 is a composite number.

Is 234567 a prime number?
If the sum of digits of a number is a multiple of 3 then it is divisible by 3. Sum of digits of 234567 = 2+3+4+5+6+7 = 27 = 3x9 So, 234567 is not a prime number because it is divisible by 3.
Below 40 a prime number the sum of its digits is 11?
what number is prime to 40 29 - it's a prime number (divisible only by 1 and itself) and if you sum the two digits 2 + 9 = 11
How do you know 273 is not a prime number?
Adding the digits together gives 12, which is divisible by 3, so 273 is divisible by 3, and thus not prime.
