Example: Find gcf of 61 and 73

Factors for 61: 1, 61
Factors for 73: 1, 73

Hence, GCf of 61 and 73 is 1

What is GCF of two numbers?

In mathematics GCF or also known as greatest common factor of two or more number is that one largest number which is a factor of those given numbers. It is represented as GCF (61, 73).

Properties of GCF

The GCF of two or more given numbers is always less than the given numbers. Eg- GCF of 61 and 73 is 1, where 1 is less than both the numbers.
If the given numbers are consecutive than GCF is always 1.
Product of two numbers is always equal to the product of their GCF and LCM.
The GCF of two given numbers where one of them is a prime number is either 1 or the number itself.

How can we define factors?

In mathematics a factor is a number which divides into another without leaving any remainder. Or we can say, any two numbers that multiply to give a product are both factors of that product. It can be both positive or negative.

Properties of Factors

Every factor of a number is an exact divisor of that number, example 1, 61 are exact divisors of 61 and 1, 73 are exact divisors of 73.
Every number other than 1 has at least two factors, namely the number itself and 1.
Each number is a factor of itself. Eg. 61 and 73 are factors of themselves respectively.
1 is a factor of every number. Eg. 1 is a factor of 61 and also of 73.

Steps to find Factors of 61 and 73

Step 1. Find all the numbers that would divide 61 and 73 without leaving any remainder. Starting with the number 1 upto 30 (half of 61) and 1 upto 36 (half of 73). The number 1 and the number itself are always factors of the given number.

61 ÷ 1 : Remainder = 0

73 ÷ 1 : Remainder = 0

61 ÷ 61 : Remainder = 0

73 ÷ 73 : Remainder = 0

Hence, Factors of 61 are 1 and 61

And, Factors of 73 are 1 and 73

Examples of GCF

Sammy baked 61 chocolate cookies and 73 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 61 and 73.
GCF of 61 and 73 is 1.

A class has 61 boys and 73 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 61 and 73. Hence, GCF of 61 and 73 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(61, 73) = ( 61 * 73 ) / LCM(61, 73) = 1.

What is the GCF of 61 and 73?

GCF of 61 and 73 is 1.

Ariel is making ready to eat meals to share with friends. She has 61 bottles of water and 73 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 61 and 73. So the GCF of 61 and 73 is 1.

Mary has 61 blue buttons and 73 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 61 and 73. Hence, the GCF of 61 and 73 or the greatest arrangement is 1.

Kamal is making identical balloon arrangements for a party. He has 61 maroon balloons, and 73 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 61 and 73. So the GCF of 61 and 73 is 1.

Kunal is making baskets full of nuts and dried fruits. He has 61 bags of nuts and 73 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 61 and 73. So the GCF of 61 and 73 is 1.
