Divisibility Rule for Grade 5:

To determine if a number is divisible by another number, you can use the following rules:

  1. Divisible by 2: A number is divisible by 2 if its last digit is 0, 2, 4, 6, or 8.

Example: 246 is divisible by 2 because its last digit is 6.

  1. Divisible by 3: A number is divisible by 3 if the sum of its digits is divisible by 3.

Example: 369 is divisible by 3 because 3 + 6 + 9 = 18, and 18 is divisible by 3.

  1. Divisible by 4: A number is divisible by 4 if the number formed by its last two digits is divisible by 4.

Example: 548 is divisible by 4 because 48 is divisible by 4.

  1. Divisible by 5: A number is divisible by 5 if its last digit is 0 or 5.

Example: 350 is divisible by 5 because its last digit is 0.

  1. Divisible by 6: A number is divisible by 6 if it is divisible by both 2 and 3.

Example: 72 is divisible by 6 because it is divisible by 2 and 3.

Divisors:

A divisor is a number that divides another number without leaving a remainder. For example, the divisors of 12 are 1, 2, 3, 4, 6, and 12.

G.C.D (Greatest Common Divisor):

The Greatest Common Divisor (G.C.D) of two or more numbers is the largest number that divides all of them without leaving a remainder.

Example: The G.C.D of 12 and 18 is 6 because 6 is the largest number that divides both 12 and 18 without leaving a remainder.

To find the G.C.D of two numbers, you can use the following methods:

  1. Prime Factorization Method: Find the prime factors of both numbers and identify the common factors. Multiply the common factors to find the G.C.D.

Example: Find the G.C.D of 24 and 36. Prime factors of 24: 2 x 2 x 2 x 3 = 2^3 x 3 Prime factors of 36: 2 x 2 x 3 x 3 = 2^2 x 3^2 Common factors: 2 x 2 x 3 = 12 G.C.D of 24 and 36 = 12

  1. Division Method: Divide the larger number by the smaller number and find the remainder. Then, divide the smaller number by the remainder. Repeat this process until the remainder is 0. The last non-zero remainder is the G.C.D.

Example: Find the G.C.D of 48 and 60. 48 ÷ 60 = 0 remainder 48 60 ÷ 48 = 1 remainder 12 48 ÷ 12 = 4 remainder 0 G.C.D of 48 and 60 = 12

Remember, divisibility rules and understanding divisors and G.C.D can help in simplifying fractions, finding common factors, and solving various mathematical problems.
