Question

If LCM (77, 99) = 693, then HCF
(77, 99) is​

Answer 1

Answer:

11

Explanation:

Product of numbers = lcm*hcf

77*99=693*x

X = 11

Hcf is 11

Answer 2

Given:

2 numbers are 77 and 99

LCM = 693

To find:

• HCF of those 2 numbers = ?

Solution:

Here we use the formula which connects both HCF and LCM that is:

HCF × LCM = Product of 2 numbers

Substitute the given values in this formula

➥ HCF × 693 = 77 × 99

➝ HCF × 693 = 7623

➝ HCF = 7623 ÷ 693

➝ HCF = 11

∴ HCF of given 2 numbers is 11

REMEMBER:

The above formula is valid only when 2 numbers are given. It cannot be used for 3 numbers.
