Those numbers are among the factors of 170.
The factors of 34 are 1, 2, 17, 34 The prime factors are 2 and 17.
composite numbers are numbers who have more than 2 factors example 10 the factors of 10 are 1,2,5,10.10 has more than 2 factors ,so it is a composite no.
The prime factors of 289 are 17 and 17 (i.e. 289 = 17*17).
The prime numbers (factors) of 34 are: 2 and 17
The prime factors of 34 are: 2, 17
The numbers that go into 17 are 1 and 17, as 17 is a prime number and only divisible by 1 and itself. The numbers that go into 20 are 1, 2, 4, 5, 10, and 20, as 20 is a composite number with multiple factors.
10 does.
Multiples of 10.
The factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The prime factors of 30 are 2, 3, and 5.
A number will always have 1 and itself as factors. And thus the only numbers with 2 factors will be prime numbers. The only prime numbers below 20 are 2, 3, 5, 7, 11, 13, 17 and 19, and thus these are the only numbers below 20 that have 2 factors.
1, 2, 17 and 34
The factors of 10 are 1, 2, 5 and 10. You need at least two numbers to find a GCF.
