Question

The hcf of two numbers is 3 and their lcm is 120. If one of the number is 15. Find the other number

Answer 1

Answer:

24

Step-by-step explanation:

We know,

Product of the two numbers = H.C.F × L.C.M

Given,

H.C.F = 3 and L.C.M = 120

So, H.C.F × L.C.M = 3×120

= 360

The first number = 15

So, the other number = 360/15

= 24

Answer 2

Answer:

Given:

HCF=3 , LCM=120 and one of the number if 15

Let the other number be X

LCM×HCF= Products of two numbers

120×3 = 15 × X

360 = 15X

360/15=X

24 = X

Therefore, the other number is 24.
