The number is 120.
7 and 8 both go into 56
120
104
Suppose the number is x. Then 2*x + 8 = 34 Subtract 8 from both sides: 2*x = 26 Divide both sides by 2: x = 13
2 and 4 can go into 8, but 13 does not go into it.
They are both prime numbers and 13-5 = 8 which is a composite number
13 is a prime number so only 13 and one can go into it
The number that both 7 and 8 can go into evenly is 56.
You said that8x = 104Divide each side of the equation by 8:x = 13
As 8 is even, and 3 is odd, I think only 1 can go into both.
16
It is: 200
The LCM of 8 and 10 is 40
The number is 120.
