How do you write 140 as the product of its prime factors?
To write any number as a product of its prime factors, we should find all those prime numbers which 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
Before we try this for given number
As now we have all prime factors, the process is complete and prime factors of
