Question

How many positive integers are factors of 120 and also factors of 40?

Answer 1

Answer:first know the .positivefactors of both

120factors are

1×120

2×60

3×40

4×30

5×24

6×20

8×15

10×12

then you need to know the factors of 40

1×40

2×20

4×10

5×8

so now the factors of 120 that are also factors of 40are 1,2,3,4,5,8,10

Step-by-step explanation:

Answer 2

40 = 2^3 x 5
No. Of positive factors = (3+1)(1+1) = 8
Since 120 is devisible by 40 , all factors of 40 will be factors of 120...
So answer is 8...
