Factors of 4700:
- If we have taken numbers from 1, 2, 3…for checking factors of 4700 we found that 4700 has factors 1, 2, 4, 5, 10, 20, 25, 47, 50, 94, 100, 188, 235, 470, 940, 1175, 2350 and 4700. Hence, we must say that 4700 is a composite number.
- Thus, 4700 is the composite number.
- If we multiply 4700 by 1, 2, 3 then we get the multiples of 4700 which are 4700, 9400 and so on.
