The sum of HCF and LCM is 915

Step-by-step explanation:

Numbers : 45 60 and 75

HCF :

5 | 45     3 | 60        5 | 75

3 | 9       2 | 20        5 | 15

3 | 3       5 | 10         3 |  3

  | 1 ​       2 |  2             |  1

                |  1

$45 = 5 \times 3 \times 3$

$60 =3 \times 2 \times 5 \times 2$

$75 = 5 \times 5 \times 3$

HCF =$5 \times 3 = 15$

LCM:

5 | 45 , 60 , 75

3 | 9 , 12 , 15

3 |  3 , 4 , 5

5 | 1  , 4 , 5

2 | 1, 4, 1

2 | 1, 2, 1

  | 1 , 1, 1

LCM =$5 \times 3 \times 3 \times 5 \times 2 \times 2=900$

Sum of HCF and LCM = 900+15=915

Hence the sum of HCF and LCM is 915
