The number is 28.
The number is 14.
1 and 7.
28*18 = 504 is one.
Halfway between 18 and 28 is (18 + 28) ÷ 2 = 23.
in a game when 18 play followed by 28 and 28 again what is the next number
2 56 4 28 8 14
46
Find the factors of all three numbers and then find the largest number that is in each list: i.e. the factors of 18 are 1, 2, 3, 6, 9, 18. So for example, to find the greatest common factor of 21, 28 and 42, find the factors of each: Factors of 21 are 1,3,7,21 Factors of 28 are 1,2,4,7,14,28 Factors of 42 are 1,2,3,6,7,14,21,42 The highest number that is in all three lists is 7. Therefore, 7 is the greatest common factor. Note: A factor is a number that divides evenly into the number. So, 2 divides evenly into 8 so 2 is a factor of 8. 3 divides evenly into 9 so 3 is a factor of 9, etc.
The ratio is 28:18 which can cancel down to 14:9
It is called a 28-digit number!
The greatest common factor is the highest number that divides exactly into two or more numbers. 14: 1, 2, 7, 14 18: 1, 2, 3, 6, 9, 18 The GCF for 14 and 18 is 2.
