The GCF of those numbers is 4. If 20 disappeared, the GCF of the remaining numbers would be 8.
4 would be the GCF of those three numbers.
You need at least two numbers to find a GCF. If that's 20 and 16, the GCF is 4.
20
Oh, isn't finding the greatest common factor like finding a happy little tree in a beautiful forest? The greatest common factor for 3, 16, and 20 is 1 because it's the largest number that divides evenly into all three numbers, just like how the sun shines on all the trees in the forest. Remember, math is just like painting, sometimes you just need to step back and see the bigger picture to find the beauty in it.
The gcf of 16 and 20 is 4. The lcm of 16 and 20 is 80
You need at least two numbers to find a GCF. IF that's 20 and 16, the GCF is 4.
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.
The GCF is 20.
gcf (greatest common factor) is usually calculated for two (or more) numbers, not for a single number.
The greatest common factor (GCF) of two numbers is the largest positive integer that divides both numbers without leaving a remainder. The GCF of 20 and 64 is 4, as both numbers can be evenly divided by 4. When you add 20 and 64 together, you get 84.
The GCF of 16 and 32 is 16.
