The prime factors of 40 are 2 and 5 To find the prime numbers of 40, you can find its prime factorization. Start with any two of its factors, such as 8 X 5. 5 is a prime number, but 8 can be factored into 4 X 2. 2 is a prime number, but 4 can be factored into 2 X 2. The prime factorization of 40 is 2 X 2 X 2 X 5, so the prime numbers in 40 are 2 and 5.
2 is a prime number because it is only divisible by 1 and itself.Ex:1*2=2It is the only even prime number and the smallest prime number!Yes and 2 is the only even prime number
The fundamental theorem of arithmetic says any integer can be factored into a unique product of primes. The is the prime factored form.
24 is composite because it can factored or split up as 24 = 3 * 8 for example. Prime numbers, such as 23, can not be split into factors.
