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
Two numbers are relatively prime if and only if they share no common proper factors (other than 1, which is a factor of all numbers). The factors of 4 are 4 and 2, while 7 has no factors other than 1 and itself. Since 4 and 7 have none of the same proper factors, they are relatively prime.
