let the required number be 'a'
we know that,
HCF x LCM= Product of two numbers
6 x 280= 30 x a
a= 6 x 280/30
a= 2 x 28
a= 56
the other number is 56
we know that,
HCF x LCM= Product of two numbers
6 x 280= 30 x a
a= 6 x 280/30
a= 2 x 28
a= 56
the other number is 56

a=30
b=x
l.c.m=280
h.c.f=6
then
a×b=l.c.m×h.c.f
![30 \times x = 6 \times 280 \\ x = 6 \times 280 \div 30 \\ \\ x = 1680 \div 30 \\ \\ x = 56 30 \times x = 6 \times 280 \\ x = 6 \times 280 \div 30 \\ \\ x = 1680 \div 30 \\ \\ x = 56](https://tex.z-dn.net/?f=30+%5Ctimes+x+%3D+6+%5Ctimes+280+%5C%5C+x+%3D+6+%5Ctimes+280+%5Cdiv+30+%5C%5C+++%5C%5C+x+%3D+1680+%5Cdiv+30+%5C%5C++%5C%5C+x+%3D+56)
x=56
b=x
l.c.m=280
h.c.f=6
then
a×b=l.c.m×h.c.f
x=56
