Given numbers are 556,646,591,726,103
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,646,591,726,103 is 1322779299204.
Find LCM of 556,646,591,726,103 with Prime Factorization
| 2 | 556, 646, 591, 726, 103 |
| 3 | 278, 323, 591, 363, 103 |
| 278, 323, 197, 121, 103 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 278 x 323 x 197 x 121 x 103 = 1322779299204
Therefore, the lowest common multiple of 556,646,591,726,103 is 1322779299204.
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.
556 x 646 x 591 x 726 x 103 = 15873351590448
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.
556 : 1, 2, 4, 139, 278, 556
646 : 1, 2, 17, 19, 34, 38, 323, 646
591 : 1, 3, 197, 591
726 : 1, 2, 3, 6, 11, 22, 33, 66, 121, 242, 363, 726
103 : 1, 103
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,646,591,726,103, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
646:2x 17x 19
591:3x 197
726:2x 3x 11x 11
103:103
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 3 = 12
Therefore, the value for common factors is 12.
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 = 15873351590448/(1x12)
LCM = 15873351590448/12
LCM = 1322779299204
Thus, we can understand that the LCM of 556,646,591,726,103 is 1322779299204.
