>Hello Sohib EditorOnline, in this article we will discuss about how to calculate the KPK (Least Common Multiple) and FPB (Greatest Common Factor) of two or more numbers. These two mathematical concepts are important in various fields such as engineering, computer science and even in our daily lives. So, let’s get started!
KPK, or Least Common Multiple, is the smallest number that is a common multiple of two or more numbers. For example, the KPK of 4 and 6 is 12, because 12 is the smallest number that is divisible by both 4 and 6.
To calculate the KPK of two or more numbers, we need to find their prime factors and then multiply the highest exponent of each prime factor. Let’s take an example to understand this:
Number
Prime Factors
Highest Exponent
12
2 x 2 x 3
2 x 1 x 1 = 2
18
2 x 3 x 3
1 x 2 x 1 = 2
24
2 x 2 x 2 x 3
3 x 1 x 1 = 3
To find the KPK of 12, 18 and 24, we multiply the prime factors with the highest exponent:
KPK = 23 x 32 = 72
So, the KPK of 12, 18 and 24 is 72.
What is FPB?
FPB, or Greatest Common Factor, is the largest number that is a factor of two or more numbers. For example, the FPB of 12 and 18 is 6, because 6 is the largest number that is a factor of both 12 and 18.
To calculate the FPB of two or more numbers, we need to find their prime factors and then multiply the lowest exponent of each prime factor. Let’s take an example to understand this:
Number
Prime Factors
Lowest Exponent
12
2 x 2 x 3
2 x 1 x 0 = 0
18
2 x 3 x 3
1 x 2 x 0 = 0
24
2 x 2 x 2 x 3
3 x 0 x 0 = 0
To find the FPB of 12, 18 and 24, we multiply the prime factors with the lowest exponent:
FPB = 20 x 30 = 1
So, the FPB of 12, 18 and 24 is 1.
How to Calculate KPK and FPB?
Step 1: Find the Prime Factors
The first step is to find the prime factors of the numbers. To do this, we can use factor trees or prime factorization method. Let’s take an example:
The second step is to identify the highest and lowest exponent for each prime factor. Let’s take an example:
Number
Prime Factors
Highest Exponent
Lowest Exponent
12
2 x 2 x 3
2 x 1 x 1 = 2
2 x 1 x 0 = 0
18
2 x 3 x 3
1 x 2 x 1 = 2
1 x 2 x 0 = 0
24
2 x 2 x 2 x 3
3 x 1 x 1 = 3
3 x 0 x 0 = 0
Step 3: Calculate the KPK and FPB
The final step is to calculate the KPK and FPB by multiplying the prime factors with the highest and lowest exponent, respectively. Let’s take an example:
KPK = 23 x 32 = 72
FPB = 20 x 30 = 1
So, the KPK of 12, 18 and 24 is 72 and the FPB is 1.
