Answer 1

❣️Hi there ❣️

$625 = {5}^{4} \\ 1125 = {5}^{3} \\ 2125 = {5}^{3} \times 17$
Therefore , HCF is 125 = 5^3 is common factor and has least power.

L.c.m is
${3}^{2} \times 17 \times {5}^{4}$

Answer 2

Hi,

Here is your answer,

625 = 5 × 5 × 5 × 5

1125 = 5 × 5 × 5

2125 = 5 × 5 × 5 × 17

    H.C.F = 5 × 5 × 3

     = 125

L.C.M = 3 × 3 × 5 × 5 × 5 × 5 × 17


Hope it helps you !
