Question

Express 70 as the product of its prime factors.

• A. $1\times 7\times 10$
• B. $2\times 5\times 7$
• C. $1\times 5\times 14$
• D. $1\times 70$

Answer 1

The correct option is B $2\times 5\times 7$

70 can be written as,
$70=1\times 70=2\times 35=2\times 5\times 7$
We can observe that 2, 5 and 7 can not be factorized further.
So, 70 can be written as $2\times 5\times 7$ as the product of its prime factors.
