If that's 23 and 5, 115 and 230
If that's 2, 3 and 5, 30 and 60
10, 20, and 30 all have factors of 2 and 5
The prime factors are: 2 x 2 x 5
As a product of its prime factors: 2*2*2*5 = 40 or as 23*5 = 40
factors: 1, 2, 5, 10, 23, 46, 115, 230prime factors: 2, 5, 23
21 has the most factors of the four numbers. 19 has 2 factors (1 and 19) 21 has 4 factors (1, 3, 7, 21) 23 has 2 factors (1, 23) 25 has 3 factors (1, 5, 25)
The prime numbers (factors) of 115 are: 5 and 23
prime factors of 60 = 2 * 2 * 3 * 5 and of 23 = 23 (23 is a prime number)
2 and 5. The factors of 50 (i.e., the whole numbers that evenly divide into 50) are 2, 5, 10, 25, and 50. Of these numbers, only 2 and 5 are prime numbers.
And in case that's 2, 3 and 5, try 30 and 60.
two numbers that have factors of 2, 5 and 7 are 70 and 140.
As a product of its prime factors it is: 2*5*5*7*23 = 8050 or as 2*52*7*23 = 8050
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.
