Their least common multiple (or their product - any multiple will do), and any multiple of that.
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.
The prime numbers (factors) of 115 are: 5 and 23
The two numbers are 9 and 23. 23-9 = 14 23-(2*9) = 5
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
If that's 23 and 5, 115 and 230 If that's 2, 3 and 5, 30 and 60
Factors refer to whole numbers, not decimals.
The number 21 would be the answer. 19 and 23 only have two factors, 1 and themselves, as they are prime numbers. 25 only has 1, 25 and 5. 21 has 1, 21, 3 and 7 for 4 possible factors.
which of the following numbers is a composite number 5,23,47,73,77,79?Another answer:77 because it has more than two factors.
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'.
They are 23 and 5
