Question

Example Find the HCF of 60, 12, 36.
60 = 4 x 15
12 = 2 x 6
= 2x 2 x 3 x 5
= 2x 2 x 3
36 = 3 x 12
= 3 x 3 x 4
= 2 * 2 * 3 * 3
.. HCF = 2 * 2 * 3 = 12
Let us work out this example in the vertical arrangement. We write all the numbers
in one line and find their factors.
2 1 60
12 | 36
.. HCF = 2 x 2 x 3 = 12

Answer 1

Answer:

let the number be x

(-6)^-1 * x = ( 9 )^-1

= > 1 / 6 * x = 1 / 9

= > x = 1 / 3 x ( - 2 ) / 1

= > - 2 / 3 .
