15 is the gfc tht the answer
Let's use the Ladder method |30, 45, 60 3|10, 15, 20 5|2, 3, 4 Now multiply 3 * 5 to get **15
**
The greatest common factor (GCF) of 30, 45, and 75 is 15. This was determined by finding the prime factorization of each number and identifying the smallest powers of their common prime factors. Therefore, GCF = 3 × 5 = 15.
