| Factor Pair | Pair Factorization |
|---|---|
| 1 and 385 | 1 x 385 = 385 |
| 5 and 77 | 5 x 77 = 385 |
| 7 and 55 | 7 x 55 = 385 |
| 11 and 35 | 11 x 35 = 385 |
Since the product of two negative numbers gives a positive number, the product of the negative values of both the numbers in a pair factor will also give 385. They are called negative pair factors.
Hence, the negative pairs of 385 would be ( -1 , -385 ) .
In mathematics, factor pair are often given as pair of numbers which when multiplied together give the original number. Every natural number is a product of atleast one factor pair. Eg- Factors of 385 are 1 , 5 , 7 , 11 , 35 , 55 , 77 , 385. So, factors of 385 in pair are (1,385), (5,77), (7,55), (11,35).
In mathematics, a factor is that number which divides into another number exactly, without leaving a remainder. A factor of a number can be positive or negative.
Hence, Factors of 385 are 1, 5, 7, 11, 35, 55, 77, and 385
No there is no even prime factor, i.e. 2, of 385.
Factors of 385 are 1 , 5 , 7 , 11 , 35 , 55 , 77 , 385. Prime factors of 385 are 5 , 7 , 11. Therefore mean of prime factors of 385 is (5 + 7 + 11) / 3 = 7.67.
Factors of 385 are 1 , 5 , 7 , 11 , 35 , 55 , 77 , 385. therefore mean of factors of 385 is (1 + 5 + 7 + 11 + 35 + 55 + 77 + 385) / 8 = 72.00.
A number x is said to be the proper divisor of y if it divides y completely, given that x is smaller than y.
An improper divisor of a number is the number itself apart from this any divisor of a given number is a proper divisor.
Factors of 385 are 1, 5, 7, 11, 35, 55, 77, 385. So, factors of 385 in pair are (1,385), (5,77), (7,55), (11,35).
Factors of 385 are 1, 5, 7, 11, 35, 55, 77, 385. Hence, the factors of 385 in pair are (1,385), (5,77), (7,55), (11,35). Therefore, in total 4 pairs of factors are possible.
Negative factors of 385 are -1, -5, -7, -11, -35, -55, -77, -385. Hence, factors of 385 in pair are (-1,-385), (-5,-77), (-7,-55), (-11,-35).
Factors of 385 are 1, 5, 7, 11, 35, 55, 77, 385. Prime factors are 5, 7, 11. So, the product of all prime factors of 385 would be 5 x 7 x 11 = 385.
Positive factors of 385 are 1, 5, 7, 11, 35, 55, 77, 385.
Prime factors of 385 are 5, 7, 11.
Factors of 385 in pair are (1,385), (5,77), (7,55), (11,35).
Factors of 385 are 1, 5, 7, 11, 35, 55, 77, 385.Factors of 385 in pair are (1,385), (5,77), (7,55), (11,35).
