101
The three-digit prime number that meets the given criteria is 373. This number is prime itself, with all its digits (3) being prime. Additionally, when considering the first two digits (37) and the last two digits (73) separately, both combinations also form prime numbers.
The largest 3 digit number whose digits are all primes is 777. The largest 3 digit number with different prime digits is 753.
963 3 is the prime 6/3=2 9/3=3 :)
11 is the only prime number with identical digits. After 11 all numbers with identical digits can be divided by atleast 11 or 3.
It is: 73 of which 7 and 3 are both prime numbers
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.
The smallest two-digit prime number whose digits themselves are prime is 23. Both 2 and 3 are prime numbers, and together they form the prime number 23.
The four numbers are: 113, 131, 151 and 191. For the product of the digits to be prime, the number must contain 2 ones - which greatly simplifies the exercise.
36,201 is not a prime number because 3 is one of its factors. 3 is one of the factors of any number whose digits add up to 3 or a multiple of 3. The only prime number with 3 as one of its factors is the number 3.
No. It is also divisible by 3, as you will see if you add the digits of the number together.
If you multiply two prime numbers, the product (result) will be a composite number, not a prime number. A prime number has exactly two factors, 1 and itself. The product of two prime numbers will have those two numbers as factors, as well. The sum of two prime numbers might be prime if one of those two numbers is 2, the only even prime number, but otherwise it will not be a prime because two odd numbers will have an even sum, which means it is divisible by 2. Examples: 2 + 3 = 5 (prime) 3 + 7 = 10 (not prime) 13 + 17 = 30 (not prime) If you multiply two prime numbers, the sum of the digits of the product might or might not be prime. Examples: 2 x 7 = 14, sum of digits is 5 (prime) 2 x 11 = 22, sum of digits is 4 (not prime) 3 x 5 = 15, sum of digits is 6 (not prime) 3 x 7 = 21, sum of digits is 3 (prime) 5 x 7 = 35, sum of digits is 8 (prime)
No. It is divisible by 3, as you will see if you add up the digits.
