Answer 2

AnsWer :

30.

Solution :

We have Pair of prime factor,

Let

• X - 2 * 3 * 3 * 5.
• Y - 2 * 3 * 5 * 7.

Now, HCF ( X, Y )

$\dashrightarrow \tt x = 2 \times 3 \times 3 \times 5. \\ \tt \dashrightarrow y = 2 \times 3 \times 5 \times 7.$

Common factor ( X, Y )

$\dashrightarrow \tt 2 \times 3 \times 5.$

$\dashrightarrow \tt 30.$

Therefore, HCF of X and Y be 30.

$\rule{200}3$

Some information :

•HCF Highest Common factor.

•LCM least Common multiple.

It's relation,

•HCF * LCM = Product of two number.
