Answer 1

Answer:

50

Step-by-step explanation:

lcm x hcf = product of the two numbers

1800 x hcf = 90000

=> 90000

hcf = ---------- = 50..

1800

hope it helps u

please mark me as brainlist

Answer 2

Answer:

two get the number =

LCM/hcf = product of two numbers

therefore, 1800/X=90000

X=90000÷1800

50

therefore ,

factors of 50

50=2×25

2×5×5

there fore,

10×5 two numbers therefore,

10×2=20

& 5×2 =10

to cross check see the LCM or HCF of 20 and 10
