a*b*c*d*e = 1050 = 2*3*5*5*7 \\ \\ \mbox{Now note carefully.2,3,7 can go to either one of} \ a,b,c,d,e \ \mbox{at the same time} \\ \\ \mbox{Thus we have} \ 5*5*5 \ \mbox{for each one of} \ 2,3,7 \\ \\ \mbox{Now} \ 5,5 \ \mbox{can go to each one of} \ a,b,c,d,e \ \mbox{as} \ 5 \ \mbox{or} \ 5^2 \\ \\ \mbox{Thus we have} \ 5*5*5*(5C_1+5C_2) = 125*15 = 1875
