the two numbers between 20 and 30 which have GCF of 4 are 24 & 28.
Prime factorization of :
24 = 2 x 2 x 2 x 3
28 = 2 x 2.......... x 7
==============
GCF=2 x 2
GCF=4
20 and any multiple of 20 are.
20 is a whole number and so it cannot lie between two consecutive whole numbers.
The sum of two numbers between 20-40 is 58. The difference is 12
To calculate the GCF you first have to split the numbers into their prime factors: 28 = 2x2x7 12 = 2x2x3 20 = 2x2x5 The next step is to identify any common factors. In this case, all three numbers have two 2s. Multiply these together and you get 4. Therefore the GCF of 28, 12 and 20 is 4.
The greatest common factor (GCF) refers to a factor that is COMMON to two or more numbers. You have only one number in the question! The greatest factor of any number is itself.
20 and any multiple of 20 will have a GCF of 20. Any multiples of 20 that differ by 20 will have a GCF of 20.
The GCF of the given two numbers is 20
The GCF of the given two numbers is 4
You need at least two numbers to find a GCF.
10, 20
Let the two numbers be x and y. Let suppose that the average of two numbers is 20. Then,x + y = 40 and 40/GCF = 5, where GCF = 40/5 = 8Since LCM is 48 and GCF is 8, the numbers are 16 and 24, whose average is 20 is true.
20 and 100.GCF is 20, and LCM is 100.
You need at least two numbers to find a GCF.
To find a GCF, you need at least two numbers. The factor rainbow of 20: 5,2,2 10,2 20
20
The general rule is that the product of the LCM and the GCF is equal to the product of the original two numbers. That would make the answer 20. Lets overlook the fact that two numbers with a GCF of 15 and an LCM of 20 don't exist.
You need at least two numbers to find a GCF. If that's 20 and 24, the GCF is 4.
