Hope this will help you..... Hey don't mind HCF is 30 &LCM is 235800

Answer 2

Answer:

HCf(3930,1800)= 30

LCM(3930,1800)=235800

Step-by-step explanation:

We have ,

2| 3930

________

3|1965

________

5|655

________

* 131

2| 1800

__________

2 | 900

__________

2 | 450

__________

5 | 225

__________

5 | 45

__________

3 | 9

__________

***3

Now,

3930= 2×3×5×131

and

1800= 2×2×2×3×3×5×5

= 2³×3²×5²

HCF(3930,1800)=2×3×5 = 30

/* Product of the smallest power of each common prime factors of the numbers */

LCM(3930,1800)= 2³×3²×5²×131

= 235800

/* Product of the greatest power of each prime factors of the numbers.
