They are factors of 28 as 28 = 4 x 7 which is also the lowest common multiple of both numbers.
1 + 2 + 4 = 7
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 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
To find the common factors of 8 and 12, we first list the factors of each number. The factors of 8 are 1, 2, 4, and 8, while the factors of 12 are 1, 2, 3, 4, 6, and 12. The common factors are 1, 2, and 4. To find the sum of these common factors, we add them together: 1 + 2 + 4 = 7. So, the sum of all the common factors of 8 and 12 is 7.
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.
umm common factors of 7& 4 is 28
