What is the greatest common factor of 21 and 35?
The GCF of 21 and 35 is 7.The factors of 21 are 1, 3, 7, and 21The factors of 35 are 1, 5, 7, and 35The greatest (largest) factor common to both 21 and 35 is 7The GCF is 7.
What is the greatest common factor of 7 21 and 35?
The GCF of 7, 21 and 35 is 7. This leaves you with 1, 3 and 5 respectively, You can go no further as the only common factor remaining is 1.The factors of 7 are: 1, 7The factors of 21 are: 1, 3, 7, 21The factors of 35 are: 1, 5, 7, 35The common factors are: 1, 7The Greatest Common Factor (GCF) is: 7
What is the greatest common factor of 21 30 and 35?
One way to determine the greatest common factor is to find all the factors of the numbers and compare them. The factors of 21 are 1, 3, 7, and 21. The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The factors of 35 are 1, 5, 7, and 35. There is only one common factor: 1. Therefore, the greatest common factor is 1. The greatest common factor can also be calculated by identifying the common prime factors and multiplying them together. The prime factors of 21 are 3 and 7. The prime factors of 30 are 2, 3, and 5. The prime factors of 35 are 5 and 7. There are no prime factors in common, so the greatest common factor is 1.
What are the common factors and greatest common factor of 35?
Short answer: There are none. There is neither a greatest common factor nor common factors of a single number, such as 35, because there cannot be any form of common factor without two or more numbers to compare. Common factors are factors that the numbers being compared have in common. The greatest common factor is the largest factor that all the numbers being compared have in common. Thus, since there are not two or more numbers to compare, there are neither common factors nor a greatest common factor. Examples: The common factors of 10 and 35 are 1 and 5; the greatest common factor is 5. The common factors of 21 and 35 are 1 and 7; the greatest common factor is 7. The common factors of 35 and 45 are 1 and 5; the greatest common factor is 5. The common factors of 35 and 49 are 1 and 7; the greatest common factor is 7. The common factors of 35 and 61 are only 1; the greatest common factor is 1.
What is the greatest common factor for 21 35 56?
Factors of 21: 1, 3, 7, 21.Factors of 35: 1, 5, 7, 35.Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56.GCF (21, 35, 56) = 7
What are common factors of 35 and 48?
First find the greatest common factors. All common factors are also factors of the greatest common factor.The greatest common factor of 48 and 35 is the same as the greatest common factor of 35 and 13 - where 13 is the remainder of the division of 48 by 35 (using Euclid's algorithm).
What is the greatest common factors of 84 and 105?
