Question

the product of two numbers is 6400. if the LCM of to numbers is 400, find their HCF

Answer 1

hi

let the two numbers be a,b

a * b = 6400

lcm = 400

hcf = ?

formula is ,

hcf = a*b / lcm

hcf = 6400 / 400

hcf = 16

Answer 2

Answer:

$\implies{16}$

Explanation:

Given:

• Product of two numbers = 6400
• LCM = 400

To Find:

• HCF = ?

We Know that,

• Product of two numbers = LCM × HCF

$\implies\:$6400 = 400 × HCF

$\implies\:$HCF = $\frac{6400}{400}$

$\implies\:$HCF = 16.
