To find the HCF of two numbers you first have to split them into their prime factors: 45 = 3x3x5 36 = 2x2x3x3 The next step is to identify any common prime factors. In this example, both numbers have two 3s as prime factors. Multiply these together and you get: 3x3 = 9 Thus the hcf of 45 and 36 is 9.
The Least Common Multiple (LCM) for 27 36 45 is 540.
The common factors of 45 and 90 are 1,3,5
The common factors of 27 and 45 are 1, 3, and 9. The greatest common factor of 27 and 45 is 9. One way to determine the common factors and greatest common factor is to find all the factors of the numbers and compare them. The factors of 27 are 1, 3, 9, and 27. The factors of 45 are 1, 3, 5, 9, 15, and 45. The common factors are 1,3, and 9. Therefore, the greatest common factor is 9. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. To then obtain the common factors, list all the factors of the greatest common factor. The prime factors of 27 are 3, 3, and 3. The prime factors of 45 are 3, 3, and 5. The prime factors in common are 3 and 3, so the greatest common factor is 3 x 3 = 9.
