Hey there!!
What are prime numbers?
Ans - Prime numbers are the numbers which has two factors. The factors would be 1 and the number it self
ex : 5 , list down the factors
1 and 5 ( observe that the factors are 1 and the number itself )
Hence, 5 is a prime number.
Note : Always remember that when you want to break a number into it's prime factors, always start with the least prime number.
Thing to remember :
The least prime number is 2 . ( the reason I am conveying this detail because most people get confused with this. Most people take the least prime number as 3 instead of 2 as 2 is the only even prime number )
Now, moving back on:
76 in to prime factors
first divide 76 with 2
=> 76 = 38 × 2
2 is a prime factor , so let's move onto 38
Divide 38 with 2
=> 76 = 19 × 2 × 2
19 is a prime factor
The final answer :
=> 76 = 19 × 2 × 2
Hope it helps!
