Question

H.C.F. of two numbers is 18 and their L.C.M is 270 . If one of those numbers is 90 then find the other 1)54 2)540 3)150 4)60

Answer 1

lcm * hcf = product of the two numbers

270 * 18 = 4860

let the other number be x

∴ 4860 = 90 * x

x = 4860 ÷ 90

x = 54

the other no. is 54

Answer 2

Hope this helps... Plz mark as brainliest...!

Hcf = 18 Lcm=270 We know that, Hcf*lcm=product of the numbers ie 18*270=90*x Therefore, x= 18*270/90 X = 54
