Answer 1

Answer:

1.5 times the HCF of 198, 396 and 270 is 27

Step-by-step explanation:

we first to find 1 time HCF of 198 , 396 , 270

now to express 198 , 396 , 270 as their prime factors

so , 198 = 2 × 3 × 3 × 11

396 = 3 × 3 × 2 × 2 × 11

270 = 3 × 3 × 3 × 2 × 5

hence the common factors of  198 , 396 , 270 are 3 , 3 , 2

then 1 time HCF of 198 , 396 , 270 is 18

then  1.5 times the HCF of 198, 396 and 270 is = 18×1.5 = 27

therefore the required HCF is 27
