A Prime number is defined as a number thats divisible only by 1 and by itself.
So you have to check ...
Is 38 divisible by 1 ?
Yes, it is 38 x 1 = 38
It 38 divisible by itself ?
Again, yes : 1 x 38 = 38
Now comes the tricky part ....
You have to find out if 38 is divisible by something else than 1 and 38 ...
Theres a rule, for example, for numbers divisible by 3 : If the sum of the individual numbers is divisible by 3, the whole number is ... but 11 isn´t divisible by 3, so 38 also isn't.
Then, wait .... 38 is an even number, since 37 and 39 aren't.
Even numbers are divisible by 2.
38 / 2 = 19
19 is a prime number.
38 isn't.
The prime factors of the number 38 are 2 and 19.
67 is a prime number; 38, like every even number greater than 2, is a composite number.
No. 76 / 2 = 38
It is a composite number.
76 is an even number so it is divisible by 2, so 2 is the first prime factor.76/2 = 38, and 38 is an even number divisible by 2, so 2is the next prime factor.38/2 = 19, and 19 is a prime number, so 19 is the next prime factor.The prime factorization of 76 is 2 x 2 x 19.
No, 38 is not a prime number because it is divisible by 1, 2, 19, and 38. A prime number is a number that is only divisible by 1 and itself.
No, it's composite. A prime number can only have thefactors 1 and itselfNo
No, it is not. A prime number is a number that is only divisible by one and itself. 38 / 2 = 19
Out of the above numbers,38 is the only number which is not prime.
The prime factors of the number 38 are 2 and 19.
38 is a Composite Number.
To express the numbers 46 and 38 as the sum of two odd primes, you can use the following combinations: For 46: 46 = 43 (a prime number) + 3 (a prime number) 46 = 41 (a prime number) + 5 (a prime number) For 38: 38 = 37 (a prime number) + 1 (a prime number) 38 = 31 (a prime number) + 7 (a prime number) So, 46 can be expressed as the sum of two odd primes in two ways, and 38 can also be expressed as the sum of two odd primes in two ways.
38 19,2
They are: 31+7 = 38
38 is a composite number. A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite.
67 is a prime number; 38, like every even number greater than 2, is a composite number.
2 x 19 = 38
