When all of them are prime numbers,then just multiply the numbers to get the LCM of those 3 numbers.
No.
30, 42, 66, 78
30, 42, 66, 78
Nobody. That is because there is no pattern to prime numbers. There are various methods to find some classes of prime numbers but none that will find all of them.
41,43, and 47 are all prime numbers. so there are three prime numbers between 40 and 50
These numbers are ALL prime.
Yes but the on prime numbers are 2,3
The given three numbers are all prime numbers
non-prime no.
No.
No.
The question, "the" three odd prime numbers, is wrong. There are much more than three odd prime numbers - in fact, infinitely many. There are infinitely many prime numbers, and all except the number 2 are odd.
There are not three prime numbers that have the sum of 3. The smallest prime number is 2. If all three prime numbers were 2, the sum would 2 + 2 + 2 = 6, so that is the smallest number that is the sum of three prime numbers.
By factoring them. Prime numbers have only two factors. Composite numbers have three or more.
30, 42, 66, 78
30, 42, 66, 78
That's an infinite list. Numbers with three factors are the squares of prime numbers.
