Write the greatest common factor in the following terms.
63p2a2r2s, – 9pq2r2s2, 15p2qr2s2, – 60p2a2rs2
उत्तर
We have,
63p2a2r2s = 3 × 3 × 7 × p × p × a × a × r × r × s
– 9pq2r2s2 = – 3 × 3 × p × q × q × r × r × s × s
15p2qr2s2 = 3 × 5 × p × p × q × r × r × s × s
– 60p2a2rs2 = – 2 × 2 × 3 × 5 × p × p × a × a × r × s × s
∴ The greatest common factor i.e. GCF is 3prs.
