Dividing 17 by the NEXT smallest prime number, 3.

• 17 ÷ 3 = 5.6 recurring, not an integer (whole number so move on to the next prime number)

Dividing 17 by the next smallest prime number, 5.

• 17 ÷ 5 = 3.4, not an integer (whole number so move on to the next prime number)

Dividing 17 by the next smallest prime number, 7.

• 17 ÷ 7 = 2.43, not an integer (whole number so move on to the next prime number)

Dividing 17 by the nextsmallest prime number, 11.

• 17 ÷ 11 = 1.55, not an integer (whole number so move on to the next prime number)

Dividing 17 by the next smallest prime number, 13.

• 17 ÷ 31 = 1.31, not an integer (whole number so move on to the next prime number)

Dividing 17 by the next smallest prime number, 17.

• 17 ÷ 17 = 1 and the search for Prime factors concludes.

So, the Prime factors of 136 are 2 and 17. And, 136 can be written as a factor of:
