Mathematics question from LCM & HCF

1. The LCM and HCF of two numbers are 8 and 48 respectively. If one of them is 24, Find the other ?

HCF x LCM = Product of Numbers

8 x 48 = 24 x the other number

other number = (8 x 48) / 24

other number = 16




 * Previously asked maths questions from numbers for competitive exams


1. Sum of two number = 16 and product = 48, find the difference of the two number ??


To solve this question, you can use the equation,

(X-Y)2  = (X+Y)2 - 4 XY

(X-Y)2 = (16)2 -  4 x 48

(X-Y)2 = 256 - 192

(X-Y)2 =  64

X-Y = 8
