Factors are the numbers that divide any given number evenly without a remainder. In daily life, we use factors for tasks like sharing items equally, arranging things, etc. In this topic, we will explore the factors of 1.5, how they are used in real life, and tips to learn them quickly.
The numbers that divide 1.5 evenly are known as factors of 1.5. A factor of 1.5 is a number that divides the number without leaving a remainder. The factors of 1.5 are 1, 1.5, and 0.5. Negative factors of 1.5: -1, -1.5, and -0.5. Prime factors of 1.5: The prime factors are 3 and 0.5. Prime factorization of 1.5: 0.5 × 3.
Factors can be found using different methods. Mentioned below are some commonly used methods: - Finding factors using multiplication - Finding factors using the 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 1.5. Identifying the numbers which are multiplied to get the number 1.5 is the multiplication method. Step 1: Multiply 1.5 by 1, 1.5 × 1 = 1.5. Step 2: Check for other numbers that give 1.5 after multiplying 0.5 × 3 = 1.5 Therefore, the positive factor pairs of 1.5 are: (1, 1.5) and (0.5, 3). For every positive factor, there is a negative factor.
Dividing the given numbers by the whole numbers until the remainder becomes zero and listing out the numbers which result in whole numbers as factors. Factors can be calculated by following a simple division method: Step 1: Divide 1.5 by 1, 1.5 ÷ 1 = 1.5. Step 2: Continue dividing 1.5 by the numbers until the remainder becomes 0. 1.5 ÷ 1 = 1.5 1.5 ÷ 0.5 = 3 Therefore, the factors of 1.5 are: 1, 0.5, and 1.5.
The factors can be found by dividing with prime numbers. We can find the prime factors using the following methods: - Using prime factorization - Using a factor tree Using Prime Factorization: In this process, prime factors of 1.5 divide the number to break it down in the multiplication form of prime factors till the remainder becomes 1. 1.5 ÷ 0.5 = 3 3 is a prime number. The prime factors of 1.5 are 0.5 and 3. The prime factorization of 1.5 is: 0.5 × 3.
The factor tree is the graphical representation of breaking down any number into prime factors. The following step shows: Step 1: Divide 1.5 by 0.5 to get 3. Here, 3 is a prime number, and it cannot be divided further. So, the prime factorization of 1.5 is: 0.5 × 3. 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 1.5: (1, 1.5) and (0.5, 3). Negative factor pairs of 1.5: (-1, -1.5) and (-0.5, -3).
Mistakes are common while finding factors. We can identify and correct those mistakes using the following common mistakes and the ways to avoid them.
There are 3 friends and 1.5 liters of juice. How much will each get if divided equally?
Each will get 0.5 liters of juice.
To divide the juice equally, we need to divide the total juice by the number of friends. 1.5/3 = 0.5
A cake weighs 1.5 kg and is divided into 3 equal parts. What is the weight of each part?
Each part weighs 0.5 kg.
To find the weight of each part, divide the total weight of the cake by the number of parts. 1.5/3 = 0.5
A rope is 1.5 meters long and needs to be cut into 3 equal pieces. How long is each piece?
Each piece is 0.5 meters long.
To find the length of each piece, divide the total length of the rope by the number of pieces. 1.5/3 = 0.5
A container holds 1.5 liters of water. If the water is poured equally into 3 bottles, how much water does each bottle hold?
Each bottle holds 0.5 liters of water.
Divide the total water by the number of bottles. 1.5/3 = 0.5
A fabric roll is 1.5 meters long and needs to be cut into 3 equal pieces. How long is each piece?
Each piece is 0.5 meters long.
Divide the total length of the fabric roll by the number of pieces. 1.5/3 = 0.5
Factors: The numbers that divide the given number without leaving a remainder are called factors. For example, the factors of 1.5 are 1, 0.5, and 1.5. Prime factors: The factors which are prime numbers. For example, 3 is a prime factor of 1.5. 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 1.5 are (1, 1.5), and (0.5, 3). Division method: A method used to find factors by dividing a number by other numbers and checking for no remainder. Prime factorization: Breaking down a number into a product of prime numbers, such as 1.5 as 0.5 × 3.
