The only square number between 20 and 30 is 25.
10, 20, 30, 40, 50...
It is: 20
20 5 30 6 42 7 Every other number is the product (multiplied) of the numbers it is between(5x6=30, 6x7=42), and the numbers between go in order (5, 6, 7) Therefor the next #s would be 56 8 72 9 90 10
30*20=600

30
30 is one such number .
The largest number that is a factor of both 20 and 30 is the greatest common factor (GCF) of the two numbers. To find the GCF, we need to determine the factors of each number. The factors of 20 are 1, 2, 4, 5, 10, and 20, while the factors of 30 are 1, 2, 3, 5, 6, 10, 15, and 30. The largest number that is common to both lists is 10, making it the largest factor of 20 and 30.
60 ( 4 ) X 15 = 60 ( 3 ) X 20 = 60 ( 2 ) X 30 = 60 ( 5 ) X 12 = 60
