Question

if h.c.f. of a and b is 12 and product of these is 1800 . find the l . c.m.?

Answer 1

HCF of a and b is 12

Product of a and b is 1800.

We know that,

HCF × LCM = product of the numbers

Let LCM be x

12 × x = 1800

12x = 1800

x = 1800/12

x = 150

Therefore, the LCM of a and b is 150.

Hope it helps

Answer 2

H.C.F. of a and b = 12
Product of a and b = 1800


         We know that HCF * LCM = a*b

So, let the LCM be x 

          Then, 12 * x = 1800

                   ⇒ x = 1800/12 = 150

So, LCM of a and b = 150
