Creative new problems of real number,

Suppose, Express each number as a product of its prime factors:

(i) 140

(ii) 156

(I). We need to calculate the product of prime factors of 140

Using the division of a number by prime numbers method

$140 = 2\times2\times5\times7$

$140=2^2\times5\times7$

(II). We need to calculate the product of prime factors of 156

Using the division of a number by prime numbers method

$156 = 2\times2\times13\times3$

$140=2^2\times13\times3$

Hence, This is required answer.
