Question

if the LCM of a and 18 is 36 and the HCF of a and 18 is 2 then a is​

Answer 1

Answer:

your answer is 4

the value of a is 4

Step-by-step explanation:

we know that HCF into LCM is equal to product of two number

so 36*2=18 *a

72=18*a

72/18=4

then value of a is 4

Answer 2

$\huge\sf\pink{Answer}$

☞ Value of a = 4

$\rule{110}1$

$\huge\sf\blue{Given}$

✭ LCM Of 2 Numbers is 36

✭ HCF of 2 Numbers is 2

✭ The Numbers are 18 and a

$\rule{110}1$

$\huge\sf\gray{To \:Find}$

◈ The Value of a?

$\rule{110}1$

$\huge\sf\purple{Steps}$

We know that,

$\underline{\boxed{\sf Product \ of \ Numbers = HCF \times LCM}}$

Substituting the Given Values,

➝ $\sf 18\times a = 2 \times 36$

➝ $\sf 18a = 72$

➝ $\sf a = \dfrac{72}{18}$

➝ $\sf\orange {a = 4}$

$\rule{170}3$
