The only common factor of 15, 2 and 5 is 1.
Factor them. 3 x 5 = 15 2 x 2 x 2 x 5 = 40 Select the common factor. The GCF is 5.
The greatest common factor of 2 and 15 is 1. 2 = 2 x 1 15 = 3 x 5 15 = 15 x 1
5 is the greatest common factor of 5 and 15. The only other common factor is 1.Since 5 is a factor of 15, it is automatically the GCF.
The GCF of 40,15 is 515 = 3 x 540 = 2 x 2 x 2 x 5-----------------------------------------------------------------------------------------------------------Another way to see it, which may be easier for you to understand is:15 = 5 x 3 (5 is a factor and 3 is a factor)40 = 5 x 8 (5 is a factor and 8 is a factor)So the answer is 5, which is the largest number (greatest common factor) that will divide evenly into 40 and 15.The GCF is 5.
Factors of 15: 1, 3, 5, 15 Factors of 50: 1, 2, 5, 10, 25, 50 Greatest common factor is 5.
The GCF is 15.
The greatest common factor of 120 and 245 is 5.
Since 5 is a factor of 15, it is automatically the greatest common factor of the pair.
Factor them. 3 x 5 = 15 2 x 2 x 3 x 5 = 60 Select the common factors. 3 x 5 = 15, the GCF.
The highest common factor is 30
The GCF is 1.
2 is not the GCF of 5 and 15.
