1 and 2.
1 x 90, 2 x 45, 3 x 30, 5 x 18, 6 x 15, 9 x 10
The factors of 75 are 1, 3, 5, 15, 25, 75 The factors of 90 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90
1,3,5,9,15,45 1,2,3,5,6,9,10,15,18,30,45,90
the only factors of 180 greater than 50 but least than 100 is 60 and 90 =)
Any of its factors
there are none, 19 is prime and it doesnt go into 90

1, 3, 5, and 15 can go into both 90 and 75. That's why they're called the "common factors" of 90 and 75.
Factors of 90 will be factors of 180.

The best way to figure this problem out is to find out all of the factors of the smaller number, which is 90. Start with the highest factor of 90 and work your way down until you find a number that goes into 756. Here is the answer. The factors of 90 are 1,2,3,5,6,9,10,15,18,30,45,90 90 does not go into 756. 45 does not go into 756. 30 does not go into 756. 18 goes into 756, so the answer is 18.
1 x 90, 2 x 45, 3 x 30, 5 x 18, 6 x 15, 9 x 10
A factor = any number which can be divided into the given number with no remainder ie 1, 2, 3, 5, 6, 10, 15, 18, 30, 45, 90 which is 11 factors 90×1 45×2 30×3 18×5 15×6 10×9
90 has more than six factors.
9: 1,3.9 90: 1,2,3,5,6,9,10,15,18,30,45,90 81: 1,3,9,27,81
The common factors of 45 and 90 are 1,3,5
