How to Find the Factors of 290?

To find the factors of 290, we will have to find the list of numbers that would divide 290 without leaving any remainder.

• 290/29 = 10; therefore, 29 is a factor of 290 and 10 is also a factor of 290.
• 290/58 = 5; therefore, 58 is a factor of 290 and 5 is also a factor of 290.

Similarly we can find other factors. Hence, the factors of 290 are 1, 2, 5, 10, 29, 58, 145, 290.

• Factors of 91 - The factors of 91 are 1, 7, 13, 91
• Factors of 38 - The factors of 38 are 1, 2, 19, 38
• Factors of 17 - The factors of 17 are 1, 17
• Factors of 51 - The factors of 51 are 1, 3, 17, 51

The number 290 is composite and therefore it will have prime factors. Now let us learn how to calculate the prime factors of 290. The first step is to divide the number 290 with the smallest prime factor, here it is 2. We keep dividing until it gives a non-zero remainder.

• 290 ÷ 2 = 145

Further dividing 145 by 2 gives a non-zero remainder. So we stop the process and continue dividing the number 145 by the next smallest prime factor. We stop ultimately if the next prime factor doesn't exist or when we can't divide any further.

So, the prime factorization of 290 can be written as 2¹ × 5¹ × 29¹ where 2, 5, 29 are prime.

Pair factors of 290 are the pairs of numbers that when multiplied give the product 290. The factors of 290 in pairs are:

• 1 × 290 = (1, 290)
• 2 × 145 = (2, 145)
• 5 × 58 = (5, 58)
• 10 × 29 = (10, 29)

Negative pair factors of 290 are:

• -1 × -290 = (-1, -290)
• -2 × -145 = (-2, -145)
• -5 × -58 = (-5, -58)
• -10 × -29 = (-10, -29)

NOTE: If (a, b) is a pair factor of a number then (b, a) is also a pair factor of that number.
