Factors of 123
We have to find the factors of number 123. Factors are the numbers which when divided by number 123we get the factors.
When we make pair of factors the multiplication of pair of factors gives the given number.
Steps to find Factors of 123:
1) Firstly we divide given number 123to 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 123
Here,
We get factors of 123 are 1, 3, 41, 123.
.We know,
A number which has more than two factors is called composite number.
A number 123has more than two factors.
Hence, 123 is composite number.
Also
We know,
A number which is not divided by any other number is called prime number.
In factors of 123 we get 3 x 41 are the prime number.
Now we find prime factorization of 123 by LCM
Prime factors of 123 = 3 x 41.
Prime factors of 123=3, 41
There are 4factors of 123 i.e.1, 3, 41, 123 .
When we make pairs of factors the multiplication of that two factors is the given number itself.
Pairs of factors of 123: (1, 123), (3,41), (41, 3), (123, 1)
Pairs of factors of 123:· 1 x 123 = 123 · 3 x 41 = 123 · 41 x 3 = 123 · 123 x 1 = 123.
We know Multiplication Property,
a x b = b x a
I.e. Pairs of factors of 123:(1, 123), (3, 41).All factors of 119=
- Prime factor of 123 =3, 41
- Sum of all factors of 121=1+3+ 41+123 =168
Pairs of factors of 123:((1, 123), (3,41), (41, 3), (123, 1) is same.
