Numbers with 3 or 5 factors are called square numbers.
That could either be "What numbers have 5 factors" or "What numbers have 2 and 5 as factors." Prime numbers to the fourth power, like 16 and 81, have 5 factors. Any multiple of 10 has 2 and 5 as a factor.
Prime numbers have two factors. 2, 3 and 5 are prime numbers.
All prime numbers have only two factors. 2, 3, 5, 7, 11
5
10,20,30,40,50,60,70,80,90
10, 20, and 30 all have factors of 2 and 5
All multiples of their lowest common multiple: lcm(3, 5, 7) = 105 → the numbers less than 400 with 3, 5, 7 as factors are: 105, 210, 315.
They are: 2 3 5 and 7 all of which are prime numbers
there are 3 no.2,3 & 5
Numbers with 3 or 5 factors are called square numbers.
1, 2, 3, 5, and 7
All of the numbers less than six can be factors, and all integers have a least one factor that is less than six. Here's a set of factors less than 6: (1, 2, 3, 4, 5)
Numbers with exactly 6 factors are perfect squares of prime numbers. The prime factorization of a number with exactly 6 factors is in the form ( p^2 ), where ( p ) is a prime number. There are 10 prime numbers less than 30: 2, 3, 5, 7, 11, 13, 17, 19, 23, and 29. So, there are 10 numbers less than 30 that have exactly 6 factors.
5 is a prime number having 1 and 5 as its only factors. It makes no difference to the factors of 5 if the digit 5 is in composite numbers.
The prime factors of 1955 are 5, 17, and 23. 5 x 17 x 23 = 1955
