Question

If the lcm and hcf of two numbers are equal and the product of two numbers is 2916 find their lcm

Answer 1

OK dude , I will explain

L. c. m X H. c. f = product of two No 's
we have Given
L. c. m= H.c.F
now
we take either H C. F or .Lcm
L. c. m. x H. C. F =2916
L. c. m X L. c. m =2916
LCM ²=2916
L. c. m =√2916
L. c. m = 54

which is also equal to H. C. F
now check
54 X 54= 2916
