The numbers that divide 7.5 evenly are known as factors of 7.5. A factor of 7.5 is a number that divides the number without remainder. The factors of 7.5 are 1, 1.5, 2.5, 3, 5, and 7.5. Negative factors of 7.5: -1, -1.5, -2.5, -3, -5, and -7.5. Prime factors of 7.5: 3 and 5. Prime factorization of 7.5: 3 × 2.5. The sum of factors of 7.5: 1 + 1.5 + 2.5 + 3 + 5 + 7.5 = 20.5

Factors can be found using different methods. Mentioned below are some commonly used methods: Finding factors using multiplication Finding factors using division method Prime factors and Prime factorization

To find factors using multiplication, we need to identify the pairs of numbers that are multiplied to give 7.5. Identifying the numbers which are multiplied to get the number 7.5 is the multiplication method. Step 1: Multiply 7.5 by 1, 7.5 × 1 = 7.5. Step 2: Check for other numbers that give 7.5 after multiplying 1.5 × 5 = 7.5 2.5 × 3 = 7.5 Therefore, the positive factor pairs of 7.5 are: (1, 7.5), (1.5, 5), (2.5, 3). All these factor pairs result in 7.5. For every positive factor, there is a negative factor.

Dividing the given numbers with the whole numbers or decimals until the remainder becomes zero and listing out the numbers which result as whole numbers or terminating decimals as factors. Factors can be calculated by following the simple division method - Step 1: Divide 7.5 by 1, 7.5 ÷ 1 = 7.5. Step 2: Continue dividing 7.5 by the numbers until the remainder becomes 0. 7.5 ÷ 1 = 7.5 7.5 ÷ 1.5 = 5 7.5 ÷ 2.5 = 3 7.5 ÷ 3 = 2.5 7.5 ÷ 5 = 1.5 Therefore, the factors of 7.5 are: 1, 1.5, 2.5, 3, 5, 7.5.

The factors can be found by dividing it with prime numbers. We can find the prime factors using the following methods: Using prime factorization Using factor tree Using Prime Factorization: In this process, prime factors of 7.5 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1. 7.5 ÷ 1.5 = 5 5 ÷ 5 = 1 The prime factors of 7.5 are 3 and 5. The prime factorization of 7.5 is: 3 × 2.5.

The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows - Step 1: Firstly, 7.5 is divided by 1.5 to get 5. Step 2: Now divide 5 by 5 to get 1. Here, 5 is the smallest prime number that cannot be divided anymore. So, the prime factorization of 7.5 is: 3 × 2.5. Factor Pairs Two numbers that are multiplied to give a specific number are called factor pairs. Both positive and negative factors constitute factor pairs. Positive factor pairs of 7.5: (1, 7.5), (1.5, 5), (2.5, 3). Negative factor pairs of 7.5: (-1, -7.5), (-1.5, -5), (-2.5, -3).

Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 7.5 are 1, 1.5, 2.5, 3, 5, and 7.5. Prime factors: The factors which are prime numbers. For example, 3 and 5 are prime factors of 7.5. Factor pairs: Two numbers in a pair that are multiplied to give the original number are called factor pairs. For example, the factor pairs of 7.5 are (1, 7.5), (1.5, 5), etc. Prime factorization: The representation of a number as the product of its prime factors. For example, the prime factorization of 7.5 is 3 × 2.5. Terminating Decimal: A decimal that ends or has a finite number of digits after the decimal point. For example, 0.5 is a terminating decimal.
