How To Find out the Factors of 49
We have to find the factors of number 49. Factors are the numbers which when divided by number 49 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 49:
1) Firstly we divide given number 49 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 49:
Here,
We get factors of 49 are 1, 7 and 49.
We know,
A number which has more than two factors is called composite number.
A number 49 has more than two factors.
Hence, 49 is composite number.
Also
We know,
A number which is not divided by any other number is called prime number.
In factors of 49 we get 7 is the prime number.
Now we find prime factorization of 49 by using LCM.
Prime factors of 49 = 7 x 7
Prime factors of 47 = 72
There are 3 factors of 49 i.e. 1, 7 and 49.
When we make pairs of factors the multiplication of that two factors is the given number itself.
Pairs of factors of 49: 1 x 49, 7 x 7.
Pairs of factors of 49: (1, 49) and (7, 7)
We know Multiplication Property,
a x b = b x a
I.e. Pairs of factors of 49: (49, 1) and (7, 7) is also same.
- All factors of 49 = 1, 7, 49.
- Prime factor of 49 = 72
- Sum of all factors of 49 = 1 + 7 + 49 = 57
Pairs of factors of 49: (1, 49) and (7, 7) also (49, 1)
