Prime factorization of

280 : 2^{3} \cdot 5 \cdot 7

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

Apply exponent rule:

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

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

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

Apply radical rule:

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

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

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

Apply radical rule:

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

2^{2} = 2

= 2 2 \cdot 5 \cdot 7

Multiply the numbers:

2 \cdot 5 \cdot 7 = 70

= 270
