Given numbers are 651,498,857,702,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 651,498,857,702,638 is 3456578651526.
Find LCM of 651,498,857,702,638 with Prime Factorization
| 2 | 651, 498, 857, 702, 638 |
| 3 | 651, 249, 857, 351, 319 |
| 217, 83, 857, 117, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 217 x 83 x 857 x 117 x 319 = 3456578651526
Therefore, the lowest common multiple of 651,498,857,702,638 is 3456578651526.
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.
651 x 498 x 857 x 702 x 638 = 124436831454936
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.
651 : 1, 3, 7, 21, 31, 93, 217, 651
498 : 1, 2, 3, 6, 83, 166, 249, 498
857 : 1, 857
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,498,857,702,638, is 1.
Now, the common factors can be found like this.
651:3x 7x 31
498:2x 3x 83
857:857
702:2x 3x 3x 3x 13
638:2x 11x 29
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 3x 3 = 36
Therefore, the value for common factors is 36.
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 = 124436831454936/(1x36)
LCM = 124436831454936/36
LCM = 3456578651526
Thus, we can understand that the LCM of 651,498,857,702,638 is 3456578651526.
