Factors are numbers that can be multiplied together to get a given number. In this blog, we will explore the factors of 147 and understand their significance in mathematics.
The factors of 147 are: 1, 3, 7, 21, 49, and 147.
To find the factors of 147, we can follow these steps:
Let's now go through a step-by-step solution to find the factors of 147.
Hence, the factors of 147 are 1, 3, 7, 21, 49, and 147.
The pair factors of 147 are the pairs of numbers that multiply together to give 147. In this case, the pair factors are (1, 147), (3, 49), and (7, 21).
Negative pair factors are the pairs of numbers where one number is positive and the other is negative, and their product is equal to 147. For 147, there are no negative pair factors since all the factors are positive.
Prime factorisation is the process of expressing a number as a product of its prime factors. To find the prime factorisation of 147, we divide it by prime numbers until we can no longer divide.
The prime factorisation of 147 is 3 * 7 * 7, where 3, 7, and 7 are all prime numbers.
Example 1: Find the factors of 147. Solution: The factors of 147 are 1, 3, 7, 21, 49, and 147.
Example 2: Determine the pair factors of 147. Solution: The pair factors of 147 are (1, 147), (3, 49), and (7, 21).
Example 3: What is the prime factorisation of 147? Solution: The prime factorisation of 147 is 3 * 7 * 7.
In mathematics, factors are numbers that divide a given number without leaving a remainder. They play a crucial role in various mathematical concepts, such as prime factorisation, finding common factors, and solving equations.
In mathematics, factors are often represented using the multiplication symbol (*) or by writing the numbers next to each other. For example, the factors of 147 can be represented as 1 * 3 * 7 * 21 * 49 * 147 or simply as 1, 3, 7, 21, 49, 147.
There are two types of factors: prime factors and composite factors.
Prime factors are the factors that are prime numbers. In the case of 147, the prime factors are 3 and 7.
Composite factors are the factors that are not prime numbers. In the case of 147, the composite factors are 1, 21, 49, and 147.
