Question

17. Find the least positive integer divisible by 20 and 24.​

Answer 1

Answer:

120

Step-by-step explanation:

prime factorisation of 20 = 2x2x5

prime factorisation of 24 = 2x2x2x3

:: 2x2x3x5=120

Answer 2

Answer:

120

Step-by-step explanation:

To find the least positive integer , we will have to find the L.C.M. of 24 and 20.

By prime factorisation method , we get

L.C.M.= 2×2×2×3×5

= 120

Hence 120 is the least positive integer divisible by 24 and 20.
