Answer 2

Answer:

Step-by-step explanation:

The LCM of the numbers 120 and 70 is :

120 = 5*2*3*2*2

70 = 5*2*7

LCM is equal to: 5*2*3*2*2*7 = 840

The HCF of the numbers 120 and 70 is:

120 = 5*2*3*2*2

70 = 5*2*7

HCF is equal to : 5*2 = 10

To verify

HCF *LCM = Product of two numbers.

10*840 = 120*70

=> 8400 = 8400

Hence verified
