1, 7, 49.
The divisors of 147 are 1, 3, 7, 21, 49, 147.
The only divisor of both is one.
The integer 49 is a composite number because it has divisors other than 1 and itself. Specifically, it can be expressed as (7 \times 7), meaning it is the square of the prime number 7. Therefore, 49 has divisors of 1, 7, and 49.
The only common divisor is 1.
The GCF is 7.
The divisors of 147 are 1, 3, 7, 21, 49, and 147.These do: 1, 3, 7, 21, 49, 147.
Answer: 2008. d(n) is number of divisors of n. I give number of divisors and list them also. The divisors of n = 2008: 1, 2, 4, 8, 251, 502, 1004, 2008 d(2008) = 8 The divisors of n = 2009: 1, 7, 41, 49, 287, 2009 d(2009) = 6
The divisors of 735 are 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, and 735.
Divisors are used to divide numbers.
2,4,8 (1 and 16 are divisors too, but the number and 1 are always divisors)
1617 is composite because it has 12 divisors: 1, 2, 7, 11, 21, 33, 49, 77, 147, 231, 539, and 1617.
All numbers of the from p2 where p is a prime. So 4, 9, 25 and 49. All the rest have fewer or more.
