Repeated Prime Factors

Repeated prime factors are discussed here.


Since, 8 = 2 × 2 × 2; here 2 is said to be repeated prime factor of 8.

A number can have two or more different repeated prime factors.


Let us consider some of the examples on repeated prime factors;

(i) The repeated prime factors of 16 = 2 × 2 × 2 × 2.

(ii) The repeated prime factors of 36 = 2 × 2 × 3 × 3.

(iii) The repeated prime factors of 27 = 3 × 3 × 3.

(iv) The repeated prime factors of 25 = 5 × 5.

(v) The repeated prime factors of 49 = 7 × 7.

(vi) The repeated prime factors of 32 = 2 × 2 × 2 × 2 × 2.

(vii) The repeated prime factors of 81 = 3 × 3 × 3 × 3.

(viii) The repeated prime factors of 108 = 2 × 2 × 3 × 3 × 3.

(ix) The repeated prime factors of 100 = 2 × 2 × 5 × 5.

(x) The repeated prime factors of 125 = 5 × 5 × 5.

(xi) The repeated prime factors of 225 = 3 × 3 × 5 × 5.
