Question

The hcf and lcm of two numbers are 18 and 252 respectively.if one of the number is 126,find the other

Answer 1

a x b = HCF x LCM

126 x b = 252 x 18
126 x b = 4536
b = 36

Hence required number is 36

Answer 2

Answer:

Other number = 36

Step-by-step explanation:

Let a and b are two numbers and h and l are HCF and LCM

respectively ,then

$\boxed {a\times b \\= h \times l }$

Now ,

a = 126, b = ?

h = 18, l = 252

$126 \times b = 18 \times 252$

$\implies b = \frac{ 18 \times 252 }{126}$

$\implies b = 18 \times 2$

$\implies b = 36$

Therefore,

Other number =(b) = 36
