Prime factorization of

945 : 3^{3} \cdot 5 \cdot 7

= 3^{3} \cdot 5 \cdot 7

Apply exponent rule:

a^{b + c} = a^{b} \cdot a^{c}

3^{3} \cdot 5 \cdot 7 = 3^{2} \cdot 3 \cdot 5 \cdot 7

= 3^{2} \cdot 3 \cdot 5 \cdot 7

Apply radical rule:

ab = a b, a \geq 0, b \geq 0

3^{2} \cdot 3 \cdot 5 \cdot 7 = 3^{2} 3 \cdot 5 \cdot 7

= 3^{2} 3 \cdot 5 \cdot 7

Apply radical rule:

a^{2} = a, a \geq 0

3^{2} = 3

= 3 3 \cdot 5 \cdot 7

Multiply the numbers:

3 \cdot 5 \cdot 7 = 105

= 3105
