What is the pattern here for numbers

From an iq test online I have trouble doing the problem:

357, 1251, 152, ?, ?, 0

I tried a common trick to ignore the spaces and add commas elsewhere but it doesn't do anything.

25, 01

Does anyone know why?

• Ignoring the first two gibberish, in the 152 there is a 2 and a 25 and the zero's last two should also be flipped like the 152 so you use a one, I guess? – Duck Aug 25 '18 at 2:48
• @u_ndefined I tried submitting it appears that it's not, thanks for picking up. – simonzack Aug 25 '18 at 5:17

     3*5, 3*7 (multiply first digit with all others)
1251
