The smallest prime is 2. In order for the difference between two primes to be 34, the other prime has to be at least 36.
Between 36 and 40 (the max allowed), only one Prime number exists: 37
In order for the difference to be 34, the first prime number must therefore be 71 or 3.
Since 71 is larger than 40, it can be excluded, leaving you with 3 instead.
So the two numbers/primes less than 40 are 37 and 3. Their difference is 34. And their product is 117
The odd primes less than 20 are: 3 5 7 11 13 17 19
There are 8 twin primes less than 100. 3,5 : 5,7 : 11,13 : 17,19 : 29,31 : 41,43 : 59,61 : 71,73

To find how many numbers less than 100 are the product of 3 distinct primes, we can consider combinations of distinct primes. The smallest three distinct primes are 2, 3, and 5, whose product is 30. The next combination, 2, 3, and 7, gives 42, and continues with combinations like 2, 5, and 7 (70) and 3, 5, and 7 (105, which exceeds 100). Thus, the valid products less than 100 are 30, 42, and 70, leading to a total of 3 such numbers.
The primes less than 10 are 2,3,5 and 7 with a product of 210.
No. The smallest 4 primes are 2, 3, 5 and 7 and their product is 210.
70
The twin primes that are greater than 20 but less than 30 are (23, 25) and (29, 31). However, since 25 is not prime, the only valid twin primes in that range are (29, 31). Twin primes are pairs of prime numbers that have a difference of two.
There 25 primes less than 100: 2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,89,97.
5 and 3 are two numbers less than 7, whose difference is 2.
The prime factors of 70 are 2,5 and 7 so their product is 70. This will happen whenever the prime factors occur only once. When we factor 70 into primes, we are asking for those primes who product is equal to 70. However, sometimes we get one or more primes raise to a power in the prime factorization. In this case, the prime raised to a power is no longer a prime so the product of prime factors is less than the number.
