As a product of its prime factors: 3*3*5*5*7 = 1575
As a product of its prime factors: 3*3*5*5*7 = 1575
1575 = 3 * 3 * 5 * 5 * 73 x 3 x 5 x 5 x 7 = 1575
Factors: 1, 3, 5, 7, 9, 15, 21, 25, 35, 45, 63, 75, 105, 175, 225, 315, 525, 1575 Prime Factors: 3*3*5*5*7
105, 210, 315, 420, and 525 have 3, 5 and 7 as prime factors. 105, 315, 525, 735 and 1575 have 3, 5 and 7 as their only prime factors.
1575 = 32 x 52 x 7
32*52*7 = 1575
3 x 3 x 5 x 5 x 7 = 1,575
You need two or more numbers to find common factors.ex. "What are the common factors of 1575 and 1780?"
Any of its factors
The GCF is 35.
Composite. A prime number is defined as "a number not divisable by any integer other than itself and 1". It can be seen that 1575 can be divided by 5,15,25,75 and maybe more. None of these numbers are 1575 or 1 so the number is composite.
