What are prime numbers from 1-150?
The prime numbers from 1 - 5 are 2, 3, and 5.
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. It is impossible to name all the prime numbers.
The sum of all prime numbers between 1 and 11 is 28.
The prime numbers from 1 to 42 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, and 41.
1, 2, 3, 7 are the prime factors of 42.
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, 42. The prime factors are 2, 3 and 7.
42 = 1 x 2 x 3 x 7
What are prime numbers from 1-150?
If the GCF of two numbers is 1 then the numbers are co-prime or a pair of numbers which have only 1 as their common factoris called co-prime.Let us check if 15 and 42 share any common factors other than 1.Factors of 15: 1, 3, 5 and 15.Factors of 42: 1, 2, 3, 6, 7, 21 and 42.As it can be seen that 3 is a common factor or GCF of 15 and 42.So, 15 and 42 are not co-prime.

No, 7 and 42 are not prime numbers. 7 is a prime number because it only has two distinct positive divisors, 1 and 7. 42 is not a prime number because it has more than two distinct positive divisors, including 1, 2, 3, 6, 7, 14, 21, and 42.
Numbers that can go into 42 are 1, 2, 3, 6, 7, 14, 21, and 42.
The numbers 7, 3, and 2 share no common denominator. They are prime numbers.
You find the prime factorization of 42 like this. You think what 2 number multiplied together give you 42: 6x7 7 is prime because the only factors it has is 1 and itself. 6 can be broken into 3x2. So you currently have 7x3x2. All these numbers are prime so you just found the prime factorization!
1, 2, 3, 4, 6, 12 2 and 3 are prime. 1, 5, 7, 35 5 and 7 are prime. 1, 2, 3, 6, 7, 14, 21, 42 2, 3 and 7 are prime.
