28, 56, 84, 112, 140, 168, 196 . . .
The first four common multiples of 4 and 7 are 28, 56, 84, and 102
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.
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.
1 + 2 + 4 = 7
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
