number theory - Partitioning integers into sets

Try to find out if it is possible to partition 6 consecutive positive integers into two sets, A1 and A2 such that the product of the elements in A1 is equal to the product of the elements in A2?



Also, check if this is possible for 20 consecutive positive integers?



I said:




Let K= positive integer, then we need to partition:



K,K+1,K+2,K+3,K+4,K+5



This wasnt helping me so i worked with numbers.



I started out with:



1,2,3,4,5,6




and i can't seem to partition it.



So i worked with:



2,3,4,5,6,7



I tried:



A1=4,7,3=84
A2=2,5,6=60




and I tried more cases but trial and error does not seem to be effective. Any strategies or patterns anybody else notice?
