Hello,
suppose the four consecutive numbers which are multiples of 5 are 5x,10x,15x,20x.
the product of these consecutive numbers is 15000, so we have;
5x×10x×15x×20x=15000;
(5×10×15×20)x⁴=15000;
15000x⁴=15000;
x⁴=15000/15000=1
so x=1
So four consecutive numbers are;
5x=5;
10x=10;
15x=15;
20x=20
Therefore four consecutive natural numbers are 5, 10, 15 and 20.
bye :-)
