The largest natural number by which the product of three consecutive even naturals is always divisible, is?

Let 10/11 = 110/N,
Then, 10N = 11 x 110
? N = (11 x 110) /10 = 121.

The first prime number is 2.

First four prime numbers are 2,3,5,7,
Their sum = (2 + 3 + 5 + 7) = 17.

Let 392/?x = 28
Then ?x = 392/28 =14
? x = 14² = 196

On dividing 13601 by 86, we get 29 as remainder
? Required number to be subtracted = 29.

Let quotient = Q and remainder = R
Then, Divisor = 12 Q =5 R
Now, R = 48
? 12Q = 5 x 48
? Q = 20

Dividend = Divisor x Quotient + Remainder
? dividend = ( 20 x 240 + 48 )
= 4848

Let the number be N
According to the question N x ( N x 3)/4 = 10800
? 3N² / 4 = 10800
? N² = (10800 x 4) / 3= 14400
N = ?14400 = 120

Let the two consecutive numbers are N and N+2

According to the question
N (N + 2) = 19043
? N² + 2N - 19043 = 0
? N² + 139N - 137N - 19043= 0
? N( N + 139) - 137 ( N - 137 ) = 0
? N( N + 139) ( N - 137) = 0
? N = 137 and N = - 139
? N = 137

Let the number be N
According to the question
N - 3N/4 = 163
? N/4 = 163
? N = 652

Let the positive number be N.
According to the question,
N + 10 = 200/N
? N² + 10N = 200
? N² + 10N - 200 = 0
? ( N - 10) ( N + 20) = 0
&ythere4; N = 10 and N = -20
But N ? -20, since N is a positive number.
So, the required number is 10.
