Answer:
3×5×53
Step-by-step explanation:
You can use divisibility rules to find the small prime factors.
The number ends in 5, so is divisible by 5.
795/5 = 159
The sum of digits is 1+5+9 = 15; 1+5 = 6, a number divisible by 3, so 3 is a factor.
159/3 = 53 . . . . . a prime number,* so we're done.
795 = 3×5×53
_____
* If this were not prime, it would be divisible by a prime less than its square root. √53 ≈ 7.3. We know it is not divisible by 2, 3, or 5. We also know the closest multiples of 7 are 49 and 56, so it is not divisible by 7. Hence 53 is prime.
I think this is find the LCM, so the answer would be 168
so what was the question again?
Answer:
Step-by-step explanation:
Let the numbers be x and y with x being the larger number.
Given,
x - y = 5
x = 5 + y
Also given,
x = 1 + 2y
5 + y = 1 + 2y
y = 4
x = 5 + y = 9
Hence, the two numbers are 9 and 4.
