Answer and Step-by-step explanation:


\huge\boxed{~LCM=8580~}

→ Prime factorization of the numbers for LCM :


15=3*5


55=5*11


52=2*2*13

→ LCM of 15, 55, 52


=2*2*3*5*11*13


=8580


\huge\boxed{~GFC=1~}

→ Prime factorization of the numbers: for GCF


15=3*5


55=5*11


52=2*2*13

→ GCF of 15, 55, 52


=1

LCM =
8580

GCF =
1

Answer:

LCM = 8580

GCF = 1

Explanation:

15 = 3 × 5

55 = 5 × 11

52 = 2 × 2 × 13

LCM(15, 55, 52)

= 2 × 2 × 3 × 5 × 11 × 13

= 8580

---------------------------------------------------

GCF explanation

The factors of 15 are: 1, 3, 5, 15

The factors of 52 are: 1, 2, 4, 13, 26, 52

The factors of 55 are: 1, 5, 11, 55

Then the greatest common factor is 1.
