Heres an example...
15 and 35
what goes into 15? what goes into 35
3 x 5 7x5
so the prime factors for 15 are 3 and 5 and 35 they are 7 and 5.
so the greatest common factor is 5.
and the prime factorization is 3x7x5^2(squared)
Prime numbers have only two factors.
Prime numbers have two and only two factors. If the number has more than two factors, it is not prime.
Prime numbers have only two factors whereas composite numbers have more than two factors
Composite numbers have more than two factors whereas prime numbers have only two factors.
Prime numbers have only two factors which are themselves and one and they add up in the same way as composite numbers which have more than two factors
All numbers that only have one and itself as factors are prime. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
Composite numbers have more than two factors some of which are prime factors but prime numbers themselves have only two factors. A prime number has only 2 factors which are itself and one A composite number has more than 2 factors
All numbers that only have one and itself as factors are prime. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
Numbers that have more than two factors are not prime numbers because prime numbers have only two factors.
Yes, all prime numbers have only two factors
13 + 11 Prime numbers are numbers only have 2 factors - 1, and itself.
All numbers that only have one and itself as factors are prime. Therefore, to tell if a certain number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
