Let LCM=432 and HCF =72
Let one number is “a”=216 and the other number is “b” which is unknown as b=?
To find b we as
LCM=a×b/HCF
LCM ×HCF /a=b putting the value we get
432×72/216=b
Therefor:
b=144
So the other number is 144.

Answer:
Here, LCM = 432, HCF = 72, First number = 216 First number x Second number = LCM x HCF ∴ 216 x Second number = 432 x 72 ∴ Second number = (432 x 72)/216 = 432 x 72/216 = 432 x 1/3 = 144 ∴ The other number is 144.
