Question: express 140 as a product of prime factor.

Answer:

140=2×2×5×7

Explanation:

To write any number as a product of its prime factors, we should find all those prime numberswhich when multiplied together form the number. Note that in such factorization, prime numbers can get repeated as well, but what is important is that

(1) all numbers are prime

(2) and their product is given number

Hence, we should divide the given number consistently by prime numbers starting with 2, which is first prime number and continue till all factors are prime numbers.

Before we try this for given number 140, let us list first few prime numbers, which are {2,3,5,7,11,13,17,19,23,29,...}

Now 140

= 2×70 (and as 70 can be divided by 2 again)

= 2×2×35

= 2×2×5×7

As now we have all prime factors, the process is complete and prime factors of 140 are 2×2×5×7.
