Question

The LCM and HCF of two numbers are 432 and 72 respectively If one of the numbers is 216 , what is the other?​

Answer 1

Answer:

144

Step-by-step explanation:

Suppose,take the other no.as y, then,

LCM × HCF = Product of the two no.

432 × 72 = 216 × y

31104 = 216 × y

y = 31104/216

y = 144

Answer 2

Answer:

____________

° Product of two number = lcm × hcf

____________________

Given :

1 number = 216

hcf = 72

lcm = 432

SOLUTION :

Let the 2nd number be x .

216 × x = 432 × 72

x = $\frac{<strong>4</strong><strong>3</strong><strong>2</strong><strong> </strong><strong>×</strong><strong> </strong><strong>7</strong><strong>2</strong>}{<strong>2</strong><strong>1</strong><strong>6</strong>}$

x = 2 × 72

x = 144

Hence , the other number will be 144 .
