Question

what is the sum of HCF and LCM of 45 60 and 75 ​

Answer 1

Step-by-step explanation:

LCM(45,60,75)=

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

HCF(45,60,75)=5×3=15

total sum=900+15=915

Answer 2

Step-by-step explanation:

45 = 3*3*5

60 = 2*2*5*3

75 = 3*5*5

HCF = 3*5 = 15

LCM = 3*3*5*5*2*2 = 900

LCM + HCF = 900+15

= 915

Answer is 915
