Answer 1

$\huge{\textsf{\textbf{\red{Answer}}}}$

✬ Other Number = 420 ✬

Step-by-step explanation:

Given:

HCF and LCM of two numbers are 12 and 5040.

One number is 144.

To Find:

What is other number ?

Solution: Let the other number be x.

As we know that

★ Product of two numbers = (HCF)(LCM) ★

A/q

HCF = 12

LCM = 5040

One number = x

⟹ x × 144 = 12 × 5040

⟹ 144x = 60480

⟹ x = 60480/144

⟹ x = 420

Hence, the other number is x = 420

★ Verification ★

➟ Product of two numbers = HCF × LCM

➟ 420 × 144 = 12 × 5040

➟ 60,480 = 60,480

Answer 2

✬ Other Number = 420 ✬

Step-by-step explanation:

Given:

• HCF and LCM of two numbers are 12 and 5040.
• One number is 144.

To Find:

• What is other number ?

Solution:

• Let the other number be x.

As we know that

• ★ Product of two numbers = (HCF)(LCM) ★

A/q

• HCF = 12
• LCM = 5040
• One number = x

⟹ x \times× 144 = 12 \times× 5040

⟹ 144x = 60480

⟹ x = 60480/144

⟹ x = 420

Hence, the other number is x = 420

Verification

→ Product of two numbers = HCF \times× LCM

→ 420 \times× 144 = 12 \times× 5040

→ 60,480 = 60,480
