1 is a factor of 30
yesYes, 3 is a factor of 30.
No, 3 is not a factor of 40.
2^3 x 3
There is no such number. If a multiple of 4 is a factor of 30, then 4 must also be a factor of 30, but 4 is not a factor of 30 (the factors of 30 are: 1, 2, 3, 5, 6, 10, 15, 30), thus no such number exists.
It is: 6
Divide the product by the factor[s] you know. The answer is the missing factor.
Firstly, we find that 2 * 3 = 6. Dividing 30 by 6, (ensuring that 6 goes in), we have 5. Since 5 is prime, 5 must be the missing prime factor.
1, 7, 49 None are missing.
25 is the missing factor of 50.
Since 30 is a factor of 60, and the largest possible factor of 30 is 30, the greatest common factor is 30.
It can be. 30 is a factor of 60.
Divide the number by one of the known factors. Then divide the quotient by another factor. Continue with all the known factors. What you are left with at the end is the missing factor.
It is the smallest factor of one (or more) of the multiplicands.
1 is a factor of 30
20 is not a factor of 30
30 is a factor of 150 so 30 is the greatest common factor of 30 and 150
