The GCF is 10.
The GCF is 10.
Factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90 Factors of 180 are 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, and 180 The factors of 90 and 180 not common to both numbers are 4, 12, 20, 36, 60, and 180.
The only common factors of 38 and 90 are 1 and 2, so it is not possible for a common factor of 38 and 90 to be greater than 2, much less 20.
The GCF of 40, 45, and 90 is 5 The factors of 40 are 1, 2, 4, 5, 8, 10, 20, and 40 The factors of 45 are 1, 3, 5, 9, 15, and 45 The factors of 90 are 1, 2, 3, 5, 6, 10, 15, 18, 30, 45, and 90 So the greatest common factor is 5.
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
Factors of 20: 1, 2, 4, 5, 10, 20.Factors of 90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90.GCF (20, 90) = 10
The GCF (greatest common factor) of 90, 20, and 95 is 5. Factors of 90: 2, 3, 4, 5, 9, 10, 18, 30, 45 Factors of 20: 2, 5, 10 Factors of 95: 5
The GCF is 10.
The GCF is 10.
1, 2, 5, and 10
Factors of 90 will be factors of 180.
Factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, and 90 Factors of 180 are 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, and 180 The factors of 90 and 180 not common to both numbers are 4, 12, 20, 36, 60, and 180.
The only common factors of 38 and 90 are 1 and 2, so it is not possible for a common factor of 38 and 90 to be greater than 2, much less 20.
20 = 22 * 590 = 2 * 32 * 5The LCM is the product of the factors of both numbers, but counting factors in common only once. Therefore, the LCM is...22 * 32 * 5= 4 * 9 * 5= 180
The GCF is 10.
90 has more than six factors.
