Their least common multiple (or their product - any multiple will do), and any multiple of that.
two numbers that have factors of 2, 5 and 7 are 70 and 140.
And in case that's 2, 3 and 5, try 30 and 60.
The prime numbers (factors) of 115 are: 5 and 23
1, 5, 23, 1151, 2, 5, 10, 23, 46, 115, 230
The factors of the set are 1,2,3,5. All three numbers are primes, so each has just two factors: itself and 1.2 = 1, 23 = 1, 35 = 1, 5
Factors refer to whole numbers, not decimals.
The two numbers are 9 and 23. 23-9 = 14 23-(2*9) = 5
If that's 23 and 5, 115 and 230 If that's 2, 3 and 5, 30 and 60
Prime numbers have two factors. 2, 3 and 5 are prime numbers.
Two of the factors of 80 are prime numbers: 2 and 5.
The two prime numbers that are factors of 55 are 11 and 5.
Since 115 ends in five, it will divide by '5'. Hence '5' is one of the factors. 5)115 = 23 Hence '23' is the other factor. Since '23' is a prime number, there are no other factors for 115 , but 5, and 23. except '1' & 115'.
