Niether. It is the median of 18 and 20.
20, is the sum of 18 and 2.
18 + 2 = 20
18: 1, 2, 3, 6, 9, 18 20: 1, 2, 4, 5, 10, 20
The GCF is 2.
The GCF is 2.
-2
2 + 18 = 20
The GCF of 18, 20, and 32 is 2. Factors of 18... 1,2,3,6,9 & 18 Factors of 20... 1,2,4,5,10 & 20 Factors of 32... 1,2,4,8,16 & 32... Therefore the GCF would be 2 !
No. If they are even numbers and not 2, they are not prime. 20 is divisible by 1, 2, 4, 5, 20, and 20. 18 is divisible by 1, 2, 3, 6, 9, and 18.
The sum of twenty and negative two is 18
