Answer:
The highest common factor is 6
Step-by-step explanation:
Each of the two numbers needs to be expressed as a product of its prime factors. In this case:
12 = 2 × 2×3
1050 = 2 ×3×5×5×7
Taking the common numbers we find that the term (2 × 3) is common in both expressions. Hence 2 × 3 = 6 is the highest common factor.
