What is the LCD of 2 3 and 7?
1 All of these numbers are primes. * * * * * That is the HCF or GCF. The LCD is 42
What is the difference of the squares of two primes is 72 what are these two primes?
Two primes whose squares have a difference of 42 are 7and 11.
How many numbers less than 100 are the product of 3 distinct primes?
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.
What are the primes between 32 and 42?
37, 41
Which set of numbers includes prime numbers only?
The set of primes would be one. The set of Mersenne primes is another. The set of all primes below 50 is another. And so on. A set which includes all primes, and only them, is the set of numbers having exactly 2 factors.
Can all numbers be factored into primes?
All composite numbers can.
What is the longest number string that only consists of prime numbers?
The longest string of consecutive numbers that are primes is two digits long, consisting of 2 and 3 only. There are no other consecutive numbers that are primes because no even numbers greater than 2 are primes.
Is 71 and 73 twin primes?
twin primes are 2 prime numbers with a difference of 2 the prime numbers 5 and 3 are twin primes because 5 minus 3 equals 2 so 109 and 111 are not twin primes
How many prime numbers are there under 1000?
There are 168 prime numbers under 1,000 . There are also 25 primes under 100, 62 primes under 300, and 95 primes under 500
Can there be three primes that are consecutive natural numbers?
No.
All co primes twin primes. True or false?
False. Co-primes are not the same as twin primes.Co-primes are any numbers having no common factorsother than 1. Examples of co-primes are 8 and 9 or 15 and 32.Twin primes are pairs of prime numbers exactly 2 apart such as 11 and 13 or 659 and 661.
Why are 3 and 5 twin primes?
Because the definition of twin primes is: two prime numbers with a difference of 2. 3 and 5 are both prime numbers, and their difference is 5 - 3 = 2 → they are twin primes.
