GCF (45, 81, 90) = 9
The greatest common factor is 15.
The GCF is 3.
30
The factors of 81 are: 1, 3, 9, 27, 81The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90The common factors are: 1, 3, 9
The GCF of 81 and 90 is: 9Definition: A factor is a divisor - a number that will evenly divide into another number. The greatest common factor of two or more numbers is the largest factor that the numbers have in common.Method: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 81 are 1, 3, 9, 27, and 81.The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90.The common factors are 1, 3, and 9. Therefore, the greatest common factor is 9.
GCF (45, 81, 90) = 9
The common factors are: 1, 3, 9
The Greatest Common Factor of 20 and 90 is 10, because the factors of 20 are: 20:1,2,4,5,10,20 The factors of 90 are: 90:1,2,3,5,6,9,10,15,18,30,45,90 So, the common factors are 1,2,5,10 10 is the greatest number of them so 10 is the Greatest Common Factor. THE ANSWER IS 10
First, find the factors: 90 = 2*3*3*5 81 = 3*3*3*3 Common factors are 3*3 = 9.
The greatest common factor is 30.
The GCF is 90.
The factors of 81 are: 1, 3, 9, 27, 81The factors of 90 are: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90The common factors are: 1, 3, 9The Greatest Common Factor (GCF) is: 9
The greatest common factor of the numbers 42, 90 and 81 is 3.
The greatest common factor is 15.
The GCF is 3.
The greatest factors of any positive integers are the numbers themselves. The greatest common factor of 75 and 90 is 15.
