The Prime Factorization Of 80

Factors of lxxx are basically the numbers that divide it evenly or exactly without leaving any remainder i.due east if a number divides lxxx with a residue of zero, then that number is called a cistron.

All Factors: 1, 2, 4, v, 8, 10, 16, 20, 40, and fourscore
Factors in pairs:(1,80),(2,40),(4,20),(5,xvi),(8,10)
Prime factors : ii, 5

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

Prime Factorization of fourscore

Prime number factorization is a method of "expressing" or finding the given number every bit the production of prime numbers. If a number occurs more than one time in prime factorization, information technology is commonly expressed in exponential class to make it more meaty.

Prime factorization of 80 : 2 x 2 x 2 ten ii x 5

Prime Factorization of 80 past Upside-Down Division Method

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

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

Upside down division method to find the factors of 80

It is chosen Upside-Down Division because the symbol is flipped upside downward.

Here, 80 is an even number. Then it is undoubtedly divisible by ii with no remainder.

Thus we do 80÷ 2 = 40. Now find the prime factors of the obtained quotient.

Repeat Step ane and Footstep ii until nosotros get a issue of prime number as the quotient.

Here, 40 is the caliber. Now detect the prime gene of 40

40÷ 2 = 20

Similarly xx÷ 2 = 10

Then 10÷ two = 5. Hither, five is the prime number.

So we can stop the process.

So, now the prime factorization of 80 with the upside-down division method is 2 × 2 × 2 × 2 × v.

Prime Factorization of 80 by Factor Tree Method

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

To use this method for a number ten,

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

And then consider 2 factors of b say c, d such that again at least one of them is a prime gene. This process is repeated until both the factors are prime i.due east if we go both the factors equally prime at any step, we stop the process there.

Post-obit is the cistron tree of the given number.

Factor tree method to find prime factors of 80

Here also we get the prime number factorisation of lxxx as 2 * two * 2 * 2 * 5 and the two prime factors are 2, v

FAQs

What are the prime factors of 80?

Its prime factors are 2, 5

Is lxxx a prime number or a composite number?

Plain, information technology is a composite number as information technology has more factors than just 1 and itself.
