lcm (3 x, 4 x) = 12 x = 180

x = \frac{180}{12} = 15

3 x = 45 = 3^{2} 5^{1}

4 x = 60 = 2^{2} 3^{1} 5^{1}

lcm (3^{2} 5^{1}, 2^{2} 3^{1} 5^{1}) = 2^{2} 3^{2} 5 = 180

t w o n u m b e r a r e 3 x a n d 4 x

l c m = x \times 3 \times 4 = 12 x

12 x = 180

x = \frac{180}{12} = 15

s o o n e i s 3 \times 15 = 45

a n o t h e r i s 4 \times 15 = 60
