3 are.
The GCF of 9, 18, and 42 is 3.The factors of 9 = 3*3The factors of 18 = 2*3*3The factors of 42 = 2*3*7So the greatest common factor = 3.
The GCF is 3.
Factors of 9: 1, 3, 9Factors of 18: 1, 2, 3, 6, 9, 18Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42GCF (9, 18, 42) = 3
Greatest common factor of 9 30 and 42 is 3.
3 is the greatest common factor of 42 and 99.
To find the greatest common factor for any group of numbers you must make a list of all the factors for each number. The factors of 18 are: 1, 2, 3, 6, 9, 18 The factors of 9 are: 1, 3, 9 Therefore, the greatest common factor of 18 and 9 is 9.
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 both numbers have in common. 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 18 are 1, 2, 3, 6, 9, and 18. The factors of 36 are 1, 2, 3, 4, 6, 9, 12, 18, and 36. The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The common factors are 1, 2, 3, and 6. Therefore, the greatest common factor is 6.
The Greatest Common Factor of 9, 18, 21: 3
The least common factor of 9, 12 and 18 is 1.
