Answer 1

120 , 90
120 = 2×2×2×3×5
90 = 2×3×3×5

LCM of 120, 90 = 2×3×5×2×2×3 = 360

HCF of 120, 90 = 2×3×5 = 30

Answer 2

Answer:

The LCM of (120,90) is 360 and HCF of (120,90) is 30.

Step-by-step explanation:

The given numbers are 120 and 90.

The numbers can be written as

$120=2\times 3\times 4\times 5$

$90=2\times 3\times 3\times 5$

The LCM of (120,90) is

$LCM(120,90)=2\times 3\times 3\times 4\times 5=360$

$HCF(120,90)=2\times 3\times 5=30$

Therefore, the LCM of (120,90) is 360 and HCF of (120,90) is 30.
