all multiples of 2 are composite numbers because they are divisible by 2

all numbers ending with 0 or 5 have 5 as a factor and are not prime numbers]]> 2016-12-17 06:11:29 UTC https://padlet.com/g5_ambika/406ywacpmq17/wish/144154032 Irya https://padlet.com/g5_ambika/406ywacpmq17/wish/144154631 Prime numbers are greater than 1. 1 is not a prime number.

Prime number is a number divisible by itself and 1.
example : 2,3,5,7 (1-10)
2 : factors 1,2
3: factors 1,3
5: factors 1,5
7: factors 1,7

2 is the only even prime number.]]> 2016-12-17 06:56:42 UTC https://padlet.com/g5_ambika/406ywacpmq17/wish/144154631 Ananyaa nissar https://padlet.com/g5_ambika/406ywacpmq17/wish/144155822 A prime number is a number divisible by 1 and the number it self.

A prime number has 2 factors, 1 and the number itself.

All numbers ending with 5 or 0 are composite numbers because they are multiples of 5.

1 is a special number because it is neither a prime or composite number.
