The GCF is the largest number that can divide two or more numbers without leaving any remainder. GCF is used to share items equally, to group or arrange items, and schedule events. In this topic, we will learn about the GCF of 5 and 14.
The greatest common factor of 5 and 14 is 1. When two numbers are co-prime, they have no common factors other than 1, so their GCF is 1. The GCF of two numbers cannot be negative because divisors are always positive.
To find the GCF of 5 and 14, a few methods are described below:
Steps to find the GCF of 5 and 14 using the listing of factors:
Step 1: Firstly, list the factors of each number.
Factors of 5 = 1, 5.
Factors of 14 = 1, 2, 7, 14.
Step 2: Now, identify the common factors.
Common factors of 5 and 14: 1.
Step 3: Choose the largest factor.
The largest factor that both numbers have is 1.
The GCF of 5 and 14 is 1.
To find the GCF of 5 and 14 using the Prime Factorization Method, follow these steps:
Step 1: Find the prime factors of each number.
Prime Factors of 5: 5 = 5
Prime Factors of 14: 14 = 2 x 7
Step 2: Now, identify the common prime factors. There are no common prime factors.
Step 3: Since there are no common prime factors, the GCF is 1.
Find the GCF of 5 and 14 using the division method or Euclidean Algorithm:
Step 1: First, divide the larger number by the smaller number.
Here, divide 14 by 5. 14 ÷ 5 = 2 (quotient), remainder = 14 − (5×2) = 4.
Step 2: Now divide the previous divisor (5) by the previous remainder (4). 5 ÷ 4 = 1 (quotient), remainder = 5 − (4×1) = 1.
Step 3: Now divide the previous divisor (4) by the previous remainder (1). 4 ÷ 1 = 4 (quotient), remainder = 0.
Since the remainder is zero, the divisor will become the GCF.
The GCF of 5 and 14 is 1.
Finding the GCF of 5 and 14 looks simple, but students often make mistakes while calculating the GCF. Here are some common mistakes to be avoided.
A gardener has 5 rose bushes and 14 sunflower plants. She wants to create rows with the same number of plants without mixing types. What is the maximum number of plants in each row?
We should find the GCF of 5 and 14.
The GCF of 5 and 14 is 1.
Each row will have 1 plant, with separate rows for roses and sunflowers.
As the GCF of 5 and 14 is 1, the gardener can make rows where each row has only 1 plant of the same type, ensuring separate rows for roses and sunflowers.
A baker has 5 loaves of bread and 14 pies. She wants to pack them in boxes with the same number of items, without mixing them. What is the maximum number of items in each box?
The GCF of 5 and 14 is 1. Each box will have 1 item, with separate boxes for bread and pies.
There are 5 loaves of bread and 14 pies.
To find the number of items in each box, we should find the GCF of 5 and 14, which is 1.
Each box will have 1 item, ensuring separate boxes for bread and pies.
A coach has 5 soccer balls and 14 basketballs. He wants to arrange them in lines with the same number of balls, without mixing types. What is the maximum number of balls in each line?
For arranging balls in lines, we have to calculate the GCF of 5 and 14.
The GCF of 5 and 14 is 1.
Each line will have 1 ball of the same type.
For arranging the maximum number of balls in lines, we need to calculate the GCF of 5 and 14, which is 1.
Each line will have 1 ball, ensuring separate lines for soccer balls and basketballs.
A festival organizer has 5 banners and 14 flags. He wants to display them in separate rows with the same number of items. What is the maximum number of items in each row?
The organizer needs equal rows.
The GCF of 5 and 14 is 1.
Each row will have 1 item, with separate rows for banners and flags.
To find the maximum number of items in each row, we find the GCF of 5 and 14, which is 1. Each row will have 1 item, ensuring separate rows for banners and flags.
If the GCF of 5 and ‘b’ is 1, and the LCM is 70, find ‘b’.
The value of ‘b’ is 14.
GCF × LCM = product of the numbers
1 × 70 = 5 × b
70 = 5b
b = 70 ÷ 5 = 14
