To find the prime factors of 490, we start by dividing it by the smallest Prime number, which is 2. 490 ÷ 2 = 245. Next, we divide 245 by the next smallest prime number, which is 5. 245 ÷ 5 = 49. Finally, 49 is a square of 7, which is a prime number. Therefore, the prime factors of 490 are 2 x 5 x 7 x 7.
