1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
Seven times.
1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315, -1, -3, -5, -7, -9, -15, -21, -35, -45, -63, -105, -315
3, 5, 7, 9 => 5x7x9 = 315
GCF(315, 1000) = 5
As a product of its prime factors: 3*3*5*7 = 315 or as 32*5*7 = 315
315 = 32*5*7
The LCF of 315 and 1,000 is 5
