Given numbers are 123,557,445,557
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 123,557,445,557 is 30487395.
Find LCM of 123,557,445,557 with Prime Factorization
557 | 123, 557, 445, 557 |
123, 1, 445, 1 |
Multiply the prime numbers at the bottom and the left side.
557 x 123 x 1 x 445 x 1 = 30487395
Therefore, the lowest common multiple of 123,557,445,557 is 30487395.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
123 x 557 x 445 x 557 = 16981479015
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
123 : 1, 3, 41, 123
557 : 1, 557
445 : 1, 5, 89, 445
557 : 1, 557
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 123,557,445,557, is 1.
Now, the common factors can be found like this.
123:3x 41
557:557
445:5x 89
557:557
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
557 = 557
Therefore, the value for common factors is 557.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 16981479015/(1x557)
LCM = 16981479015/557
LCM = 30487395
Thus, we can understand that the LCM of 123,557,445,557 is 30487395.
