Warm Up 1- Problem 4
Archis on Tue Oct 07, 2008 7:02 am
Dear users of this forum,
I would like to poise for discussion Problem 4 of Warm-up 1: "How many factors of 1000 are multiples of 20?"
The following was my answer:
Do you guys have any faster methods or concepts to share?

I would like to poise for discussion Problem 4 of Warm-up 1: "How many factors of 1000 are multiples of 20?"
The following was my answer:
- Spoiler:
- Express 1000 as 20*50
From there you realize all you need next is to find how many factors are there of 50, to find the how many factors of 1000 are also multiples of 20.
These factors would be 1,50,2,25,5,and 10 for a total of 6 factors
Do you guys have any faster methods or concepts to share?
