The GCF is 1.
To determine what number goes into 5, 7, and 8, we need to find the greatest common factor (GCF) of these three numbers. The GCF is the largest number that divides evenly into all three numbers. In this case, the GCF of 5, 7, and 8 is 1, as there are no common factors other than 1 among these numbers. Therefore, the number that goes into 5, 7, and 8 is 1.
7 and 35 (35 = 5*7)
2^3 x 3^2 x 5 = 360 You need at least two numbers to find a GCF.
GCF(1, 5, 10) = 1. The GCF of any set of numbers containing 1 must be 1.
A number pair whose GCF is the same as one of the numbers is i , i x j where i and j are integers greater than zero. If i=3 and j=5 then the number pair will be 3,15. The GCF is 3. If i=7 and j=11 the number pair will be 7,77 and the GCF 7. The number of possible solutions is infinite.
5 and 7
5 and 60 have a gcf of 5 and a LCM of 60
5 and 75 15 and 25
Pick a pair of numbers. Let's try 30 and 42. Their GCF is 6. 6 x 5 and 6 x 7 By the distributive property, that can be written as 6(5 + 7)
Since the number 5 is prime, the Greatest Common Factor of the three numbers is 1.
The GCF of 75 and 80 is 5. The GCF of a pair of numbers can't be greater than their difference, which is 5 in this case. Since 5 is a factor of both 75 and 80, it is the GCF. 75/5= 15 80/5=16 The GCF is 5.
5 or 10
The GCF is 1.
The GCF of 5 and 10 is 5.
The above is completely true. However, factoring problems in textbooks are usually arranged to have one correct answer. The thing these sorts of problems want you to remember is that the product of the GCF and the LCM of a pair of numbers is the same as the product of the numbers. If you are given the GCF and LCM of a pair of numbers, multiply them together. The numbers will be another factor pair of that product.
The GCF is 5.
