The greatest common multiple of any set of integers is infinite.
60
To find the least number divisible by 23456 with a remainder of 1, you need to find the least common multiple (LCM) of 23456 and the number 1 more than it. The LCM of two numbers is the smallest number that is a multiple of both numbers. In this case, you would calculate the LCM of 23456 and 23457. The LCM can be found by multiplying the two numbers and then dividing by their greatest common divisor.
Any multiple of 60.
23456-56789 = -33333
There is no "most common multiple". To find all common multiples, you start by finding the least common multiple. All other common multiples are multiples of this least common multiple.
23456 + 654321 = 677,777
23456 + 758 = 24214
No, it can't. 18 is not a factor of 23456
"most common multiple" is not a recognised mathematical term. 48 is a common multiple, but it is not the Least Common Multiple (LCM).
The most common multiple of any set of integers is infinite.
If you mean the lowest common multiple then it is 280
There is no "most common" multiple of two or more numbers, but there is a greatest common multiple if that's what you mean. But for multiples, the list of common ones goes on and on and on, since every single number in the universe is a multiple.
