Given numbers are 516,678,556,951,781
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 516,678,556,951,781 is 2006565040524.
Find LCM of 516,678,556,951,781 with Prime Factorization
| 2 | 516, 678, 556, 951, 781 |
| 2 | 258, 339, 278, 951, 781 |
| 3 | 129, 339, 139, 951, 781 |
| 43, 113, 139, 317, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 43 x 113 x 139 x 317 x 781 = 2006565040524
Therefore, the lowest common multiple of 516,678,556,951,781 is 2006565040524.
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.
516 x 678 x 556 x 951 x 781 = 144472682917728
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.
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
678 : 1, 2, 3, 6, 113, 226, 339, 678
556 : 1, 2, 4, 139, 278, 556
951 : 1, 3, 317, 951
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 516,678,556,951,781, is 1.
Now, the common factors can be found like this.
516:2x 2x 3x 43
678:2x 3x 113
556:2x 2x 139
951:3x 317
781:11x 71
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 2x 3x 3 = 72
Therefore, the value for common factors is 72.
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 = 144472682917728/(1x72)
LCM = 144472682917728/72
LCM = 2006565040524
Thus, we can understand that the LCM of 516,678,556,951,781 is 2006565040524.
