Question

the product of LCM and HCF of two numbers is 80 one of the numbers is 20 find the number​

Answer 1

Answer:

Let the no. Be x

Product of LCM and HCF = product of numbers.

80=20*x = x =80/20=4.

Hope it will help you.

Answer 2

Answer:

if one number is 20 ,the other number is 4.HCF = 2*2=4. LCM =2*2*5=20

Step-by-step explanation:

the product of two numbers = there HCF * LCM

so, x*20 = 80, or

x= 80/20 = 4

if one number is 20 ,the other number is 4

check , factor of

4 =2*2

20=2*2*5

HCF = 2*2=4. LCM =2*2*5=20. correct
