Factors of 50

Factors of 50 are basically the numbers that divide it evenly or exactly without leaving any remainder i.e if a number divides 50 with a remainder of zero, then that number is called a factor.

• All Factors: 1, 2, 5, 10, 25, and 50
• Factors in pairs : (1,50), (2,25), and (5,10)
• Prime factors : 2, 5

Now, let us see the prime factors and prime factorization of the number.

Prime Factorization of 50

Prime factorization is a method of “expressing” or finding the given number as the product of prime numbers. If a number occurs more than once in prime factorization, it is usually expressed in exponential form to make it more compact.

Here Prime factorization comes out to be 2 x 5 x 5

Prime Factorization of 50 by Upside-Down Division Method

Upside-Down Division is one of the techniques used in the Prime factorization method to find factors of numbers.

In this method, you will divide a given “composite” number evenly by the several prime numbers(starting from the smallest) till it gets a prime number.

It is called Upside-Down Division because the symbol is flipped upside down.

Here, 50 is an even number. So it is undoubtedly divisible by 2 with no remainder.

Thus we do 50÷ 2 = 25.  Now find the prime factors of the obtained quotient. 

Repeat Step 1 and Step 2 until we get a result of prime number as the quotient.

Here, 25 is the quotient. Now find the prime factor of 25

25÷ 5 = 5. Here, 5 is the prime number.

So we can stop the process.

So, now the prime factorization of 50 with the upside-down division method is 2 × 5 × 5.

Prime Factorization of 50 by Factor Tree Method

The Factor tree method is another technique for producing the prime factorization and all factors of a given number.

To use this method for a number x,

Firstly consider two factors say a,b of x such that a*b is equal to x and at least one of them (a, b) is a prime factor say a.

Then consider two factors of b say c, d such that again at least one of them is a prime factor. This process is repeated until both the factors are prime i.e if we get both the factors as prime at any step, we stop the process there.

Following is the factor tree of the given number.

So here also we get the prime factorisation as 2 * 5 * 5 and the two prime factors are 2, 5
