Question

Find the prime factorization of 210. 2 X 3 X 5 X 7 2 X 3 X 35 2 X 7 X 15

Answer 1

Answer: 2 X 3 X 5 X 7

Step-by-step explanation:

The given number to find the prime factorization =210

We know that 210 can be written as $21\times10$

Also , 21 can be written as $3\times7$.

And 10 can be written as $2\times5$

Then , the  prime factorization of 210 is given by :-

$210=21\times10\\\\=3\times7\times2\times5$

Hence, the prime factorization of 210= 2 X 3 X 5 X 7

Answer 2

The answer is:  [A]:  " 2 × 3 × 5 × 7 " .

210 = 70 * 3 ;

70 * 3 = 35 * 2 * 3 ;

35* 2* 3 = 7 * 5 * 2 * 3 ; which corresponds to "Answer choice:  [A]." .
