The sum is 84 and the GCF is 6
3 (21+5)
The Greatest Common Factor is 3
2(24 + 7)
The sum is: 5+1 = 6
The GCF is 7.
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.
They are: GCF = 5 and LCM = 325 and the sum is 5+325 = 330
The sum is 335.
The sum is 84 and the GCF is 6
9(2 + 3)
3 (21+5)
11(5 + 6)
5(8 + 5)
9(2 + 3)
7(7 + 9)
This question requires more information in order for it to make any sense at all! You cannot have a sum of a number: you need two or more numbers. A single number cannot have a GCF. The GCF needs to be COMMON to two or more numbers.
