Since 27 is a factor of 81, it is automatically the GCF.It is: 27
The greatest common factor (GCF) of 27, 36, and 81 is 9. To find the GCF, we need to determine the largest number that divides evenly into all three numbers. In this case, 9 is the largest number that is a factor of 27, 36, and 81, making it the greatest common factor.
The least common factor of two numbers is the smallest positive integer that both numbers can be evenly divided by. In this case, the factors of 81 are 1, 3, 9, 27, and 81, while the factors of 243 are 1, 3, 9, 27, 81, and 243. The least common factor of 81 and 243 is 81, as it is the smallest factor that both numbers share.
The GCF of 54 and 81 is 27One way to determine the greatest common factor is to find all the factors of the numbers and compare them.The factors of 54 are 1, 2, 3, 6, 9, 18, 27, and 54.The factors of 81 are 1, 3, 9, 27, and 81.The common factors are 1, 3, 9, and 27. Therefore, the greatest common factor is 27.The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together.The prime factors of 54 are 2, 3, 3, and 3.The prime factors of 81 are 3, 3, 3, and 3.The prime factors in common are 3, 3, and 3, so the greatest common factor is 3 x 3 x 3 = 27. Factors of 54: 1 2 3 6 9 18 27 54 Factors of 81: 1 3 9 27 81 The GCF of 54 and 81 is 27The Greatest Common Factor (GCF) is: 27 .27.
Their greatest common factor is 27
