This is the factor tree of 270: 270 / \ 3 90 / \ 3 30 / \ 3 10 / \ 2 5 The 3's, 2, 5 would be prime so you would circle them.
The factors of 270 are 1, 2, 3, 5, 6, 9, 10, 15, 18, 27, 30, 45, 54, 90, 135, 270. For them to be common, they need to be compared to another set of factors.
The GCF of 5, 110, 270, and 460 is 5. The solution is quite easy: the only factors of 5 are 1 and 5, so those are the only possible GCFs for the set. We see that 5 is a factor of 110, 270, and 460 because each ends in a zero, so 5 is the GCF.
2 x 3 x 3 x 3 x 5 = 270
using whole numbers 1*2*3*3*3*5=270
As a product of its prime factors: 2*3*3*3*5 = 270
Since 45 is a factor of 270, it is automatically the GCF.
whenever you start the factor tree always divide by the lowest number possible first... 2 * 5 * 3 * 3 * 3 = 270 2 = 2 5 = 5 9 = 3 * 3 * 3
The greatest common factor of 270 and 360 is 90.
the highest common factor of 225 and 270 is: 45
Greatest common factor of 140 and 270 is 10.
The factors of 270 are: 1 2 3 5 6 9 10 15 18 27 30 45 54 90 135 270 (135,2)(90,3)(54,5)(45,6)(30,9)(27,10)(18,15)
