Question

i want to see who can do this The h.c.f. And l.c.m. of two numbers are 13 and 1989 respectively. If one of them numbers is 117, Determine the other. challenge

Answer 1

Answer:

221

Step-by-step explanation:

let the two numbers are a,and b

a=117, b=?b

hcf =13

lcm =1989

product of the given numbers= lcm * hcf

a x b =lcm x hcf

117 x b= 1989 x 13

b= $\frac{1989*13}{117}$

b=17 x 13

b=221

therefore  second number =b=221

Answer 2

Answer:

Another number is 221.

Explanation:

We know that product of two numbers = Product of HCF and LCM

Product of LCM and LCM = 1989*13 = 25857

One number = 117

So, another number = 24857/117 = 221
