Answer 1

Answer:

L.C.M. = 720 & H.C.F. = 24

To find:

Find the lowest common multiple (LCM) and highest common factor (HCF) of 120 and 144 by fundamental theorem of arithmetic.

Solution:

HCF is a largest number that “divides exactly into two or more numbers”.

LCM is two numbers is the “smallest number that they both divide evenly into”.

120=2 \times 2 \times 2 \times 3 \times 5120=2×2×2×3×5

144=2 \times 2 \times 2 \times 2 \times 3 \times 3144=2×2×2×2×3×3

H C F=2 \times 2 \times 2 \times 3=24HCF=2×2×2×3=24

L C M=2 \times 2 \times 2 \times 2 \times 3 \times 3 \times 5=720LCM=2×2×2×2×3×3×5=720
