1900 = 22 x 52 x 191
Why don't you start looking for obvious factors. For every 0 in a number, you have a factor of 10 - which has the prime factors 2 and 5.
The GCF is 2.
1900 * .2 = 380

38, as a percentage of 1900 = 100*38/1900 = 2%
(1900+2000) ÷ 2 = 1950
As a product of its prime factors: 2*2*5*5*19 = 1900 or as 22*52*19 = 1900
