Answer 1

a=2³×3

=8×3

=24

b=2×3×5

=30

LCM of a b c= 2 | 24, 30, 3^n × 5

=3 | 12, 15, 3^n × 5

2 | 4, 5, 3^n × 5

2 | 2, 5, 3^n × 5

5 | 1, 5, 3^n ×5

3^n | 1, 1, 3^n ×1

| 1, 1, 1

=2×3×2×2×5×3^n=2³×5×3^n+1

2³×5×3^n+1=2³×3²×5

=5×3^n+1=2³×3²×5/2³

=3^n+1=3²×5/5

=3^n=3²¯¹

=n=3¹/3

=n=3/3

=n=1
