They are: 2+4 = 6
The factors of 35 are: 1x35 and 7x5 add the factors 1+35+7+5= 48
1 and 5
40+40 = 80 and 40*40 = 1600
40
29
20 + 20
40,=1,2,4,5,8,10,20 AND 40
40 and 40
Two factors of 40 are 20 and 2. There are no more factors of 2, but factors of 20 include 5 and 4. There are no more factors of 5 but 4 factors of 4 include 2 and 2. So, the factors of 40 are 2, 5, 2, 2 This simplifies to make 2^3 * 5 Hope that helped :)
The factors for 40 are 1,2,4,5,8,10,20,40 The factors for 50 are 1,2,5,10,25,50
40
The factors of 40 are 1,2,4,5,8,10,20 and 40. For them to be common, they need to be compared to another set of factors.
