Question

the lcm of two numbers is 4080 and their hcf is 136 .If one of the number is 680 ,find the other number​

Answer 1

Step-by-step explanation:

LCM×HCF= Product of two numbers

4080×136= 680× other number

Other number = 4080×136/680

=554880/ 680

=816.

Answer 2

$\textrm{LCF of two numbers \times HCF of two numbers = Product of two numbers}$

$\longrightarrow\rm{4080\times 136 = 680\times b}\longrightarrow\rm{554880 = 680\times b}$

$\longrightarrow\rm{b=554880/680=816}$
