Prime numbers go on forever.
127 prime numbers in that range. See related link for prime numbers up to 10000. Plus there is a link to download Zip files of prime numbers up to 1 million.
83, 3,and 2 are prime numbers which add up to 88.
137 and 11 are two prime numbers that add up to 148.
They are: 3*7*11 = 231
3 x 7 x 11 = 231
To determine factors of a number it is necessary to divide the number by prime numbers of increasing value. If there is no remainder then the prime number is a factor. The square root of 231 is approximately 15 so it is necessary to divide by all the prime numbers up to 13 (15 is not a prime number). 231 ÷ 2 leaves a remainder of 1 231 ÷ 3 divides exactly 77 times (which is 7 x 11 - both are prime numbers) 231 ÷ 5 leaves a remainder of 1 231 ÷ 7 divides exactly 33 times (which is 3 x 11 - both are prime numbers) 231 ÷ 11 divides exactly 21 times (which is 3 x 7 - both are prime numbers) 231 ÷ 13 leaves a remainder of 10 If we multiply together the three numbers that are shown to be factors 3 x 7 x 11 = 231 this confirms that there are no other factors of 231 except 1 and 231 itself. This last condition is true for every positive integer. 231 is divisible by 1, 3, 7, 11 and 231
2x2x3x3x7=252
38 = 2 x 19
As a product of its prime factors: 2*3*7 = 42
They are: 1 times 107 = 107 which is also a prime number
No. Prime factors are the numbers that make up other numbers, but they have to be prime. Prime factorisation is the process of finding the prime numbers that create a number. This is when you multiply the prime numbers together and the product is the original number. For example: 20 5x4 5x2x2 This process is called prime factorisation. In this case, the prime numbers are 2, 2, and 5.
168 = 2 * 2 * 2 * 3 * 7
They are: 3*7*11 = 231
They are only: 1 times 2003 = 2003 because it is a prime number
