### Numbers ( Quantitative Aptitude)

Prime Numbers: A number greater than 1 is called a prime number, if it has exactly two factors, namely 1 and the number itself.
Composite Numbers: Numbers greater than 1 which are not prime are known as composite numbers.
Co-primes: Two numbers a and b are said to be co-primes, if their H.C.F. is 1. e.g., (2, 3), (4, 5), (7, 9), (8, 11), etc. are co-primes,
TESTS OF DIVISIBILITY
Divisibility By 2: A number is divisible by 2, if its unit's digit is any of 0, 2, 4, 6, 8.
Divisibility By 3: A number is divisible by 3, if the sum of its digits is divisible by 3.
Divisibility By 4: A number is divisible by 4, if the number formed by the last two digits is divisible by 4.
Divisibility By 5: A number is divisible by 5, if its unit's digit is either 0 or 5.
Divisibility By 6: A number is divisible by 6, if it is divisible by both 2 and 3.
Divisibility By 8: A number is divisible by 8, if the number formed by the last three digits of the given number is divisible by 8.
Divisibility By 9: A number is divisible by 9, if the sum of its digits is divisible by 9.
Divisibility By 10: A number is divisible by 10, if it ends with 0.
Divisibility By 11: A number is divisible by 11, if the difference of the sum of its digits at odd places and the sum of its digits at even places is either 0 or a number divisible by 11.
Divisibility by 12: A number is divisible by 12, if it is divisible by both 4 and 3.
Divisibility By 14: A number is divisible by 14, if it is divisible by 2 as well as 7.
Divisibility By 15: A number is divisible by 15, if it is divisible by both 3 and 5.
Divisibility By 16: A number is divisible by 16, if the number formed by the last 4 digits is divisible by 16.
Divisibility By 24: A given number is divisible by 24, if it is divisible by both 3 and 8.
Divisibility By 40: A given number is divisible by 40, if it is divisible by both 5 and 8.
Divisibility By 80: A given number is divisible by 80, if it is divisible by both 5 and 16.
Note: If a number is divisible by p as well as q, where p and q are co-primes, then the given number is divisible by pq.
If p and q are not co-primes, then the given number need not be divisible by pq, even when it is divisible by both p and q.

(xn - an ) is divisible by (x - a) for all values of n.
(xn - an) is divisible by (x + a) for all even values of n.
(xn + an) is divisible by (x + a) for all odd values of n.

Arithmetic Progression (A.P.) : If each term of a progression differs from its preceding term by a constant, then such a progression is called an arithmetical progression. This constant difference is called the common difference of the A.P.
An A.P. with first term a and common difference d is given by a, (a + d), (a + 2d),(a + 3d),.....
The nth term of this A.P. is given by Tn =a (n - 1) d.
The sum of n terms of this A.P. Sn = n/2 [2a + (n - 1) d] = n/2   (first term + last term).
(1 + 2 + 3 +…. + n) =n(n+1)/2
(12 + 22 + 32 + ... + n2) = n (n+1)(2n+1)/6
(13 + 23 + 33 + ... + n3) =n2(n+1)2/4
Geometrical Progression (G.P.) : A progression of numbers in which every term bears a constant ratio with its preceding term, is called a geometrical progression.
The constant ratio is called the common ratio of the G.P. A G.P. with first term a and common ratio r is :
a, ar, ar2, ………..
In this G.P. Tn = arn-1
Sum of the n terms, Sn=   a(1-rn)/ (1-r)
