How To Find out the Factors of 38
We have to find the factors of number 38. Factors are the numbers which when divided by number 38 we get the factors.
When we make pair of factors the multiplication of pair of factors gives the given number.
Steps to find Factors of 38:
1) Firstly we divide given number 38 to get remainder 0.
2) After getting answers all numbers we get are called Factors of given number.
3) 1 is the only number having factor of all numbers.
4) The given number itself is the highest factor of given number.
We find factors of 38:
Here,
We get factors of 38 are 1, 2, 19 and 38.
We know,
A number which has more than two factors is called composite number.
A number 38 has more than two factors.
Hence, 38 is composite number.
Also
We know,
A number which is not divided by any other number is called prime number.
In factors of 38 we get 2and 19 are the prime number.
Now we find prime factorization of 38 by using LCM.
Prime factors of 38 = 2 x 19
There are 4 factors of 38 i.e. 1, 2, 19 and 38.
When we make pairs of factors the multiplication of that two factors is the given number itself.
Pairs of factors of 38: 1 x 38, 2 x 19.
Pairs of factors of 38: (1, 38) and (2, 19)
We know Multiplication Property,
a x b = b x a
I.e. Pairs of factors of 38: (38, 1) and (19, 2) is also same.
- All factors of 38 = 1, 2, 19, 38.
- Prime factor of 38 = 2 x 19
- Sum of all factors of 38 = 1 + 2 + 19 + 38 = 60
- Pairs of factors of 38: (1, 38) and (2,19) also (38, 1) and (19, 2)
