What is GCF of 143 and 208?


Steps to find GCF of 143 and 208

Example: Find gcf of 143 and 208

  • Factors for 143: 1, 11, 13, 143
  • Factors for 208: 1, 2, 4, 8, 13, 16, 26, 52, 104, 208

What does GCF mean in mathematics?

Greatest Common Fcator (GCF) or also sometimes written as greates common divisor is the largest number that can evenly divide the given two numbers. GCF is represented as GCF (143, 208).

Properties of GCF

  • The GCF of two given numbers where one of them is a prime number is either 1 or the number itself.
  • GCF of two consecutive numbers is always 1.
  • Given two numbers 143 and 208, such that GCF is 13 where 13 will always be less than 143 and 208.
  • Product of two numbers is always equal to the product of their GCF and LCM.

What is the definition of factors?

In mathematics, factors are number, algebraic expressions which when multiplied together produce desired product. A factor of a number can be positive or negative.

Properties of Factors

  • Every number is a factor of zero (0), since 143 x 0 = 0 and 208 x 0 = 0.
  • Every number other than 1 has at least two factors, namely the number itself and 1.
  • Every factor of a number is an exact divisor of that number, example 1, 11, 13, 143 are exact divisors of 143 and 1, 2, 4, 8, 13, 16, 26, 52, 104, 208 are exact divisors of 208.
  • Factors of 143 are 1, 11, 13, 143. Each factor divides 143 without leaving a remainder.
    Simlarly, factors of 208 are 1, 2, 4, 8, 13, 16, 26, 52, 104, 208. Each factor divides 208 without leaving a remainder.

Steps to find Factors of 143 and 208

  • Step 1. Find all the numbers that would divide 143 and 208 without leaving any remainder. Starting with the number 1 upto 71 (half of 143) and 1 upto 104 (half of 208). The number 1 and the number itself are always factors of the given number.
    143 ÷ 1 : Remainder = 0
    208 ÷ 1 : Remainder = 0
    143 ÷ 11 : Remainder = 0
    208 ÷ 2 : Remainder = 0
    143 ÷ 13 : Remainder = 0
    208 ÷ 4 : Remainder = 0
    143 ÷ 143 : Remainder = 0
    208 ÷ 8 : Remainder = 0
    208 ÷ 13 : Remainder = 0
    208 ÷ 16 : Remainder = 0
    208 ÷ 26 : Remainder = 0
    208 ÷ 52 : Remainder = 0
    208 ÷ 104 : Remainder = 0
    208 ÷ 208 : Remainder = 0

Hence, Factors of 143 are 1, 11, 13, and 143

And, Factors of 208 are 1, 2, 4, 8, 13, 16, 26, 52, 104, and 208

Examples of GCF

Sammy baked 143 chocolate cookies and 208 fruit and nut cookies to package in plastic containers for her friends at college. She wants to divide the cookies into identical boxes so that each box has the same number of each kind of cookies. She wishes that each box should have greatest number of cookies possible, how many plastic boxes does she need?

Since Sammy wants to pack greatest number of cookies possible. So for calculating total number of boxes required we need to calculate the GCF of 143 and 208.
GCF of 143 and 208 is 13.

A class has 143 boys and 208 girls. A choir teacher wants to form a choir team from this class such that the students are standing in equal rows also girls or boys will be in each row. Teacher wants to know the greatest number of students that could be in each row, can you help him?

To find the greatest number of students that could be in each row, we need to find the GCF of 143 and 208. Hence, GCF of 143 and 208 is 13.

What is the difference between GCF and LCM?

Major and simple difference betwen GCF and LCM is that GCF gives you the greatest common factor while LCM finds out the least common factor possible for the given numbers.

What is the relation between LCM and GCF (Greatest Common Factor)?

GCF and LCM of two numbers can be related as GCF(143, 208) = ( 143 * 208 ) / LCM(143, 208) = 13.

What is the GCF of 143 and 208?

GCF of 143 and 208 is 13.

Ariel is making ready to eat meals to share with friends. She has 143 bottles of water and 208 cans of food, which she would like to distribute equally, with no left overs. What is the greatest number of boxes Ariel can make?

The greatest number of boxes Ariel can make would be equal to GCF of 143 and 208. So the GCF of 143 and 208 is 13.
