The common factors are: 1, 2, 4, 7, 14, 28
The word "greatest" is a superlative. What that means is that there can only be one gcf. So there are not greatest common factors of 4 and 7, there is a GCF, which is 28.
Because 7 is a prime number, its only factors are 1 and 7. 7 is not a factor of 4 or 8, so 1 must be the only factor common to all four numbers. To work it out in detail: Factors of 4: 1 2 4 Factors of 7: 1 7 Factors of 8: 1 2 4 8 Factors of 14: 1 2 7 14 The GCF of 4, 7, 8, and 14 is 1
To find common factors, find all the factors of each number. Then a common factor is any number that appears in both lists. Factors of 56 1, 2, 4, 7, 8, 14, 28, 56 Factors of 35 1, 5, 7, 35 Therefore the common factors of 56 and 35 are 1 and 7.
the greatest common factor is 7, because 21 divided by 7 is 3, 28 divided by 7 is 4 and 56 divided by 7 is 8.
The LCF of 4 & 7 is... 1 ! There are no other common factors.
The factors of 4 are 1, 2, and 4. The factors of 7 are 1 and 7. The only common factor is 1.
The only factor common to 7 and 4 is 1 because 7 is prime.
Factors of 4: 1, 2, 4 Factors of 7: 1, 7 GCF (4, 7) = 1
The common factors of 4 and 34 are 1 and 2
The factors of 21 are: 1, 3, 7, 21The factors of 28 are: 1, 2, 4, 7, 14, 28The common factors are: 1, 7
Factors that are the same for two or more numbers are their common factors.What numbers are factors of both 7 and 8?Factors of 7 are 1, and 7.Factors of 8 are 1, 2, 4, and 8.Common factors are the numbers that are in both lists.So, 1 is the common factor of 7 and 8.
The common factors are: 1, 2, 4, 7, 14, 28
The common factors are: 1, 2, 4, 7, 14, 28
The common factors are: 1, 2, 4, 7, 14, 28.
The factors of 63 are 1,3,7,9,21, and 63 The factors of 56 are 1,2,4,7,8,14,28 and 56. The factors that are shared are 1 and 7. So the common factors of 63 and 56 are 1 and 7.
The factors of 7 are: 1, 7The factors of 84 are: 1, 2, 3, 4, 6, 7, 12, 14, 21, 28, 42, 84The common factors are: 1, 7
