20 and any multiple of 20 are.
40 and 60
which pair of numbers from 1 to 30 has the LCM OF 120
The numbers are 18 and 20.
The numbers are: 7 and 20
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 328 = 2 x 2.......... x 7==============GCF=2 x 2GCF=4
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.
20 and 100.GCF is 20, and LCM is 100.
4 and 40 8 and 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 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 4
The GCF of the given two numbers is 20
10 and 20, among others. -- Pick any multiple of 10. -- Add 10 to it. -- There you have two numbers whose GCF is 10.
You need at least two numbers to find a GCF.
10, 20
4 and 24 are. 8 and 20 are too. 12 and 16 are as well.
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
