4= 1,2,4
7= 1,7
The factors of 4 are 1, 2, and 4. The factors of 7 are 1 and 7. The only common factor is 1.
Let us list the factors of 28. 28 = 2*2*7 = 4 * 7. 4 + 7 = 11 The two factors are 4 and 7. ==============================
Factors of 4: 1, 2, 4 Factors of 7: 1, 7 GCF (4, 7) = 1
The LCF of 4 & 7 is... 1 ! There are no other common factors.
The factors of 7 are 1 and 7. The factors of 12 are 1, 2, 3, 4, 6, and 12.
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
1, 2, 4, 7, 14 and 28 are its factors, so it has six factors.
The factors of 7 are: 1, 7The factors of 14 are: 1, 2, 7, 14
if 4 * 7 = x * 4, then x = (4 * 7) / 4 = 7
The factors of 35 are : 35, 7, 5, 1 The factors of 56 are : 56, 28, 14, 8, 7, 4, 2, 1 The common factors are 7 and 1 The greatest common factor is 7.
The previous answer is as follows: The factors of 28 are: 28, 1, 7 and 4. ---------------------------------------------------------- Edited Answer: The factors of 28 are 1, 2, 4, 7, 14, and 28
The factors of 28 are: 1, 2, 4, 7, 14, 28 The factors of 42 are: 1, 2, 3, 6, 7, 14, 21, 42 The factors of 63 are: 1, 3, 7, 9, 21, 63
