No is divisible by 7 if n is divided by 2 3 4 5 the remainder is 1 what is the smallest value that n could b

kvv77 [185]

Answer: $301$

Step-by-step explanation:

Since, The LCM of numbers given numbers $2$ , $3$ , $4$ and $5$ is $60$ .

Thus, the number that gives 1 as reminder and is the multiple of 7 is $60 n + 1$

Where n is any positive integer,

Since, For $n = 5$ ,

The number is, $60\times 5 + 1 = 300 + 1 = 301$

Which is divisible by $7$ .

Thus, the required number is 301.

Note : For n = 1, 2 3 and 4, numbers are 61, 121, 181 and 241

But they are not the multiple of 7.

Please answer with process

$\mathsf{Given : a - b = 5}$

$\mathsf{Squaring\;on\;both\;sides,\;we\;get :}$

$\mathsf{\implies (a - b)^2 = 5^2}$

$\mathsf{\implies a^2 + b^2 - 2(a.b) = 25}$

$\mathsf{Given : a^2 + b^2 = 29}$

$\mathsf{\implies 29 - 2(a.b) = 25}$

$\mathsf{\implies 2(a.b) = 29 - 25}$

$\mathsf{\implies 2(a.b) = 4}$

$\mathsf{\implies (a.b) = 2}$
