Answer 1

Answer:

Step-by-step explanation:

3. product of HCF &LCM= product of two numbers

let 2nd no. be x

9072=72×x

x=9072/72

x=126

therefore other number is 126

3. 144 * x = 12 * 5040

x = (12*5040)/144 = 420

4. 72 = 2x2x2x3x3

84 = 2x2x3x7

The LCM = 2x2x2x3x3x7 = 504.

Check 504/ 72 = 7. Correct

504/84 = 6 Correct

5. You need to determine the factor of 510 and 425 which will be:

510 = 2 * 3 * 5 * 17

425 = 5 * 5 * 17

Highest common factor or HCF of both the number will be 17

Hence, the highest number that can divide both 510 and 435 will be 17.
