The common factors of 21 42 and 84 are 21
42 prime factors -----> 2,3,7 105 prime factors -----> 3,5,7 There is 3 and 7 in common : There fore 3*7 = 21; 21 is the greatest common factor.
The common factors of 21, 42, and 56 are: 1 and 7
21 itself is the greatest common integral factor, since 21 X 2 = 42.
Factors of 15: 1, 3, 5, 15. Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42. GCF (15, 42) = 3
The common factors of 21 and 42 are 3, 7 and 21. The greatest common factor (GCF) is 21.
The greatest common factor of 42 depends upon the other numbers with which 42 has COMMON factors. However, the greatest common factor HAS to be one of the factors of 42 which are: 1, 2, 3, 6, 7, 14, 21, 42.
The greatest common factor is 21
Factors of 21: 1, 3, 7, 21 Factors of 42: 1, 2, 3, 6, 7, 14, 21, 42 GCF (21, 42) = 21
The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42 The factors of 63 are: 1, 3, 7, 9, 21, 63 The factors of 105 are: 1, 3, 5, 7, 15, 21, 35, 105 The common factors are: 1, 3, 7, 21 The Greatest Common Factor: GCF = 21
The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42 The factors of 63 are: 1, 3, 7, 9, 21, 63 The factors of 105 are: 1, 3, 5, 7, 15, 21, 35, 105 The common factors are: 1, 3, 7, 21 The Greatest Common Factor: GCF = 21
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 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The factors of 105 are 1, 3, 5, 7, 15, 21, 35, and 105.The common factors are 1, 3, 7, and 21. Therefore, the greatest common factor is 21.The GCF of 42 and 105 is 21
The GCF of 42 and 86 is 2. 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 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The factors of 86 are 1, 2, 43, and 86. The common factors are 1 and 2. Therefore, the greatest common factor is 2.
The common factors of 21 42 and 84 are 21
The common factors of 21 and 42 are the numbers that divide both 21 and 42 without leaving a remainder. The factors of 21 are 1, 3, 7, and 21, while the factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42. The common factors of 21 and 42 are 1, 3, 7, and 21.
The Greats Common Factor (GCF) is 21 63: 1,3,7,9,21,63 42: 1,2,3,67,14,21,42 21: 1,3,7,21 They all number 21 listed in there the Factors
Answer: 42Definition: 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 42 are 1, 2, 3, 6, 7, 14, 21, and 42.The factors of 126 are 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, and 126.The common factors are 1, 2, 3, 6, 7, 14, 21, and 42. Therefore, the greatest common factor is 42.
