The prime factors of 75 are 3, 5, 5 3 x 5 x 5 = 75
Not all (5 is prime) but every multiple of 5 greater than 5 is composite because they have more than two factors. Every multiple of any integer greater than one is composite.
The LCM of 5 and 14 is 70, which is the multiple of the combined prime factors of both numbers (2 x 5 x 7).7070
5*5*5*2. 5 and 2 are the only prime factors of 250, so you must multiple these together in order to find prime factorization.
45 is a composite since it factors are 5 and 9.
75 is a multiple of 5 that has 6 factors.
The factors of 5 are 1 and 5. Neither is a multiple of 8.
Any multiple of 5.
The prime factors of 75 are 3, 5, 5 3 x 5 x 5 = 75
3 and 5 are factors of 15. 15 is a common multiple of 3 and 5.
5, 10, and 20 are all multiples of 5 and factors of 20.
1) The product of those numbers 2) Any multiple of point (1)
Since 2, 3, and 5 are all factors of 30, they're factors of every multiple of 30.
3 and 5 are factors of 3270
30
5 is the only multiple of 5 that is also a factor of 25
Their least common multiple (or their product - any multiple will do), and any multiple of that.
