What is GCF of 58 and 87?


Steps to find GCF of 58 and 87

Example: Find gcf of 58 and 87

  • Factors for 58: 1, 2, 29, 58
  • Factors for 87: 1, 3, 29, 87

Hence, GCf of 58 and 87 is 29

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 (58, 87).

Properties of GCF

  • Given two numbers 58 and 87, such that GCF is 29 where 29 will always be less than 58 and 87.
  • GCF of two numbers is always equal to 1 in case given numbers are consecutive.
  • The product of GCF and LCM of two given numbers is equal to the product of two numbers.
  • The GCF of two given numbers is either 1 or the number itself if one of them is a prime number.

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

  • Each number is a factor of itself. Eg. 58 and 87 are factors of themselves respectively.
  • 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, 2, 29, 58 are exact divisors of 58 and 1, 3, 29, 87 are exact divisors of 87.
  • 1 is a factor of every number. Eg. 1 is a factor of 58 and also of 87.
  • Every number is a factor of zero (0), since 58 x 0 = 0 and 87 x 0 = 0.

Steps to find Factors of 58 and 87

  • Step 1. Find all the numbers that would divide 58 and 87 without leaving any remainder. Starting with the number 1 upto 29 (half of 58) and 1 upto 43 (half of 87). The number 1 and the number itself are always factors of the given number.
    58 ÷ 1 : Remainder = 0
    87 ÷ 1 : Remainder = 0
    58 ÷ 2 : Remainder = 0
    87 ÷ 3 : Remainder = 0
    58 ÷ 29 : Remainder = 0
    87 ÷ 29 : Remainder = 0
    58 ÷ 58 : Remainder = 0
    87 ÷ 87 : Remainder = 0

Hence, Factors of 58 are 1, 2, 29, and 58

And, Factors of 87 are 1, 3, 29, and 87

Examples of GCF

Sammy baked 58 chocolate cookies and 87 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 58 and 87.
GCF of 58 and 87 is 29.

A class has 58 boys and 87 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 58 and 87. Hence, GCF of 58 and 87 is 29.

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(58, 87) = ( 58 * 87 ) / LCM(58, 87) = 29.

What is the GCF of 58 and 87?

GCF of 58 and 87 is 29.

Mary has 58 blue buttons and 87 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 58 and 87. Hence, the GCF of 58 and 87 or the greatest arrangement is 29.

Kamal is making identical balloon arrangements for a party. He has 58 maroon balloons, and 87 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 58 and 87. So the GCF of 58 and 87 is 29.

Kunal is making baskets full of nuts and dried fruits. He has 58 bags of nuts and 87 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 58 and 87. So the GCF of 58 and 87 is 29.

To energize public transportation, Abir needs to give a few companions envelopes with transport tickets, and metro tickets in them. On the off chance that he has 58 bus tickets and 87 metro tickets to be parted similarly among the envelopes, and he need no tickets left. What is the greatest number of envelopes Abir can make?

To make the greatest number of envelopes Abir needs to find out the GCF of 58 and 87. Hence, GCF of 58 and 87 is 29.
