Question

the LCM and HCF of two numbers at 240 and 12 respectively if one of the number is 160 then find the other number (grade 10 CH 1)

Answer 1

just use the formula and u will reach ur Answer.

forumula

hcf*lcm=product of two no.
240*12=160*x
x={240*12}/160
x=18

Answer 2

Method 1:

= > (240 * 12)/160

= > 2880/160

= > 18.


Method 2:

Let the other number be x.

Given that LCM of two numbers is 240 and HCF of 2 numbers is 12.

= > We know that LCM * HCF = product of two numbers

= > 240 * 12 = 160 * x

= > 2880 = 160 * x

= > 2880/160 = x

= > 18 = x


Therefore the other number = 18.



Hope this helps!
