## Related Questions     The HCF of 48 and 72 is 24. The LCM is 144.       32 = 2^5 144 = 2^4 * 3^2 hcf (or rather, gcd) = 2^4 = 16  The perimeter (measured in cm) is the length around so you would just add 144 + 162 + 144 + 162. The area (measured in sq. cm) is how much the surface covers. It is just multiplying 144 x 162. The HCF of 144 and 192 is 48. The LCM is 576.    If you mean the HCF of 144 and 180 equals 13m-3 then the value of 'm' is 3   In order to find the common factors of 144 and 100, we follow the following steps:Step 1: Find the HCF of 144 and 100.Prime factorization of 144 = 2x2x2x2x3x3Prime factorization of 100 = 2x2x5x5HCF(144,100) = 2x2 = 22 = 4.Step 2: Find the factors of HCF(144,100) i.e. 4. The factors of 4 are the common factors of 144 and 100.Factors of 4 are 1, 2 and 4.So, common factors of 144 and 100 are 1, 2 and 4. They are 18, 36, 54, 72, 90, 108, 126, 144 and 162.  ###### Math and ArithmeticFactoring and MultiplesPercentages, Fractions, and Decimal ValuesChemistryAlgebra Copyright © 2020 Multiply Media, LLC.
