Question

if n= 10800, then the number of divisors which are multiple of 15​

Answer 1

Answer:

30 Divisors

Step-by-step explanation:

if n= 10800, then the number of divisors which are multiple of 15​

10800 = 15 * 720

720

= 1 * 720

= 2 * 360

= 3 * 240

= 4 * 180

= 5 * 144

= 6 * 120

= 8 * 90

= 9 * 80

= 10 * 72

= 12 * 60

= 15 * 48

= 16 * 45

= 18 * 40

= 20 * 36

= 24 * 30

30 Divisors which are multiple of 15

Answer 2

Answer:30

Step-by-step explanation:

"For factors to be multiples of 15, we must select atleast one ‘3’ (3 ways) and one ‘5’ (2 ways), and any number of ‘2’s (5 ways). The required number is 5 x 3 x 2 = 30."
