Question

if LCM 77,99 equal to 693 then HCF 77,99 is dash

Answer 1

--------------------------------------------------------------------------------------------------------------

Let H.C.F is x.

We have,

L.C.M = 693, Numbers = 77 and 99

L.C.M * H.C.F = Product of two numbers

693 * x = 77 * 99

693 x = 7623

x = 7623 / 693

x = 11.

H.C.F of 77 and 99 is 11.

Answer 2

Answer:

11

Step-by-step explanation:

Concept

• The full form of LCM in Maths is the Least common multiple. LCM is the smallest number which is divisible by two or more given numbers.
• The full form of HCF in Maths is the Highest Common Factor. HCF of two or more numbers is the greatest factor that divides the numbers.

Given

LCM 77,99 equal to 693

Find

HCF 77,99 is

Solution

$\mathrm{HCF} \times \mathrm{LCM}= product of numbers$

$\mathrm{HCF} \times 693=77 \times 99$

$\mathrm{HCF}=\frac{7623}{693}=11$
