Answer 1

$\huge\color{red}\boxed{\colorbox{black} {Aɳʂɯҽɾ°᭄}}$

GIVEN:

◌ HCF of two numbers is 23

◌ LCM of two numbers is 1449

TO FIND:

◌ If, first number is 161 then second number is ?

FORMULA:

◌ HCF (a,b) × LCM (a,b) = a×b

SOLUTION:

◌ Let the two numbers be a and b

◌ Let a = 161

◌ We have to find b.

$⇒23 \times 1449 = 161 \times b$

$⇒23 \times \frac{1449}{161} = b$

$⇒b = 23 \times 9$

$\huge\pink{ ∴ \: b = 207}$

ᴛʜᴜs, ᴛʜᴇ sᴇᴄᴏɴᴅ ɴᴜᴍʙᴇʀ ɪs 207.
