What is GCF of 43 and 100?


Steps to find GCF of 43 and 100

Example: Find gcf of 43 and 100

  • Factors for 43: 1, 43
  • Factors for 100: 1, 2, 4, 5, 10, 20, 25, 50, 100

Hence, GCf of 43 and 100 is 1

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 (43, 100).

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 43 and 100, such that GCF is 1 where 1 will always be less than 43 and 100.
  • 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 43 x 0 = 0 and 100 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, 43 are exact divisors of 43 and 1, 2, 4, 5, 10, 20, 25, 50, 100 are exact divisors of 100.
  • Factors of 43 are 1, 43. Each factor divides 43 without leaving a remainder.
    Simlarly, factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, 100. Each factor divides 100 without leaving a remainder.

Steps to find Factors of 43 and 100

  • Step 1. Find all the numbers that would divide 43 and 100 without leaving any remainder. Starting with the number 1 upto 21 (half of 43) and 1 upto 50 (half of 100). The number 1 and the number itself are always factors of the given number.
    43 ÷ 1 : Remainder = 0
    100 ÷ 1 : Remainder = 0
    43 ÷ 43 : Remainder = 0
    100 ÷ 2 : Remainder = 0
    100 ÷ 4 : Remainder = 0
    100 ÷ 5 : Remainder = 0
    100 ÷ 10 : Remainder = 0
    100 ÷ 20 : Remainder = 0
    100 ÷ 25 : Remainder = 0
    100 ÷ 50 : Remainder = 0
    100 ÷ 100 : Remainder = 0

Hence, Factors of 43 are 1 and 43

And, Factors of 100 are 1, 2, 4, 5, 10, 20, 25, 50, and 100

Examples of GCF

Sammy baked 43 chocolate cookies and 100 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 43 and 100.
GCF of 43 and 100 is 1.

A class has 43 boys and 100 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 43 and 100. Hence, GCF of 43 and 100 is 1.

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(43, 100) = ( 43 * 100 ) / LCM(43, 100) = 1.

What is the GCF of 43 and 100?

GCF of 43 and 100 is 1.

Ariel is making ready to eat meals to share with friends. She has 43 bottles of water and 100 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 43 and 100. So the GCF of 43 and 100 is 1.

Mary has 43 blue buttons and 100 white buttons. She wants to place them in identical groups without any buttons left, in the greatest way possible. Can you help Mary arranging them in groups?

Greatest possible way in which Mary can arrange them in groups would be GCF of 43 and 100. Hence, the GCF of 43 and 100 or the greatest arrangement is 1.

Kamal is making identical balloon arrangements for a party. He has 43 maroon balloons, and 100 orange balloons. He wants each arrangement tohave the same number of each color. What is the greatest number of arrangements that he can make if every balloon is used?

The greatest number of arrangements that he can make if every balloon is used would be equal to GCF of 43 and 100. So the GCF of 43 and 100 is 1.

Kunal is making baskets full of nuts and dried fruits. He has 43 bags of nuts and 100 bags of dried fruits. He wants each basket to be identical, containing the same combination of bags of nuts and bags of driesn fruits, with no left overs. What is the greatest number of baskets that Kunal can make?

the greatest number of baskets that Kunal can make would be equal to GCF of 43 and 100. So the GCF of 43 and 100 is 1.
