Step-by-step explanation:

Answer 2

answer is 20

FIRST WE SHOULD REMEMBER THAT WE SHOULD ALWAYS USE PRIME NUMBERS( NUMBER S WHICH ARE NOT DIVISBLE with ANOTHER NUMBER) LIKE 2,3 OR 7 etc

400=2×200

200=2×100

100=2×50

50=2×25

25=5×5

5= 5×1

So numbers are 2×2×2×2×5×5

Taking common : 2 ×2 ×5 = 10×2 = 20
