Answer 2

Answer:

Second Number = 30

Step-by-step explanation:

HCF × LCM = First Number × Second Number

=> 10 × 60 = 20 × Number 2

=> 600 = Number 2 × 20

=> Number 2 = 600 / 20

Hence ;

Second Number = 30

Proof :

LCM of two numbers 20 & 30

2 |_20 , 30

5 |_10 , 15

2 |_ 2 , 3

|_ 1 , 3

LCM of 20 & 30 = 2 × 5 × 2 × 1 × 3 = 60
