| 2 | 70 | Â | 2 | 120 |
|---|---|---|---|---|
| 5 | 35 | 2 | 60 | |
| 7 | 7 | 2 | 30 | |
| Â | 1 | 3 | 15 | |
| Â | Â | 5 | 5 | |
| Â | Â | Â | 1 | |
| Â | Â | Â | Â |
Thus, \(70 = 2 \times 5 \times 7\),
\(120 = 2 \times 2 \times 2 \times 3 \times 5\)
Common factors are one set of \(2\) and \(5\).
Hence, the Highest Common Factor = \(2 \times 5 = 10\)
