Answer:
18
Step-by-step explanation:
90 = 18·5
126 = 18·7
180 = 18·10
990 = 18·55
The greatest common factor of these numbers is 18.

<em>Comment on the GCF</em>
It can be useful to know Euclid's algorithm for finding the GCF:
- Determine the remainder from dividing the larger number by the smaller.
- If the remainder is zero, the smaller number is the GCF. If the remainder is non-zero, use it to replace the larger number and repeat from step 1.
For example, 126 mod 90 = 36; 90 mod 36 = 18; 36 mod 18 = 0, so 18 is the GCF of 126 and 90. (The modulo function 'mod' returns the remainder from division.)
Answer:
The answer is 19.
Step-by-step explanation:
This is because the sequence adds up by 7 each time. Have a nice day!
Answer:
Circumference = diameter × π
Take π =3. 14
Answer:
Imagine that the number that we are looking for is x
We know that:
x/5 - 78 = 9
x/5 = 9 + 78
x/5 = 87
x = 87 . 5 = 435
So the number we need is 435
Answer:
16 / C
Step-by-step explanation:
-4 x -4 = 16
4 x 4 = 16
two negatives cancel out when multiplying, that is why it equals 16*
