first three common factors of 3,4,5
24, 48, 72
9 and 21 only have two common factors: 1 and 3.
The common factors are: 1, 2, 3, 4, 6, 12
The only common factor is 1.
1, 2 and 5
Common factors of: - 30 = 1,3,5,10,15,30 45 = 1,3,5,15,45 105 = 1,3,5,7,15,21,35,105 So the common factors in all three numbers are 1,3,5 & 15.
114, 228, 342
There are only 2, and these are 1 and 2.
Yes, three and eight are prime to each other, meaning they are coprime. This is because their greatest common divisor (GCD) is 1; they do not share any positive integer factors other than 1. Since 3 is a prime number and 8 is a composite number, they have no common factors.
The first three multiples of 9 are 9, 18 and 27. For them to be common, they need to be compared to another set of factors.
Eight factors.
