Which two numbers make 33?

1×33 = 33. 3x **11** = 33. 11×3 = 33. 33×1 = 33.

What are the first 5 prime numbers? First five prime numbers: **2, 3, 5, 7 and 11** . A prime number is an integer or whole number that has only two factors – 1 and itself. In other words, a prime number can only be divided equally by 1 and itself. Prime numbers must also be greater than 1.

**What is a factor of 45?**

All the factors of 45 are 1, 3, 5, 9, 15 and 45. Prime factor of 45 45 . is **= 3 ^{2} × 5** .

What is the biggest factor?

The largest factor of any number is the **number itself** .

What is the biggest factor? The greatest common factor (GCF) of a set of numbers is **the greatest factor that all numbers share** . For example, 12, 20 and 24 have two common factors: 2 and 4. The greatest is 4, so we say that the GCF of 12, 20 and 24 is 4. GCF is often used to find the common denominator.

What is the GCF for 12 and 18? In terms of numbers, the greatest common factor (GCF) is the greatest natural number that divides two or more natural numbers. Example 1: **6** is the greatest common factor of 12 and 18.

**What is the greatest common divisor of 18 and 27?**

The GCF of 18 and 27 is **9** . To calculate the greatest common factor (GCF) of 18 and 27, we need to factor each number (18 = 1, 2, 3, 6, 9, 18; 27 = 1, 3, 9, 27) and Choose the greatest factor that exactly divides both 18 and 27, i.e. 9.

What is the GCF of 18 30? 4 and 18 have 30 common factors, which are 1, 2, 3 and . are **6** . Therefore, the greatest common factor of 18 and 30 is 6.

How do you find MCM and LCM?

The formula showing the relationship between their LCM and HCF is: **LCM(a,b)×HCF(a,b)=a×b** . For example, let us take two numbers 12 and 8. Let’s use the formula: LCM(12,8) × HCF(12,8) = 12 × 8. The LCM of 12 and 8 is 24; And the HCF of 12 and 8 is 4.

What is the greatest common factor of 30 18 and 6? As you can see when you list the factors of each number, **6** is the largest number that divides 6, 18 and 30.

**How do you get rid of HCF?**

The HCF of two or more numbers is the highest common factor of the given numbers. This is found by **multiplying the common prime factors of the given numbers** . Whereas the least common multiple (LCM) of two or more numbers is the smallest number among all the common multiples of the given numbers.

How do you find the LCD? To use the greatest common factor to solve the problem, you must first multiply the two denominators together. Divide this product by GCF. After finding the product of two denominators, **divide that product by the GCF you found earlier** . This number will be your least common denominator (LCD).
