Find LCM of 855,689,912,605,518 with Prime Factorization
| 2 | 855, 689, 912, 605, 518 |
| 3 | 855, 689, 456, 605, 259 |
| 5 | 285, 689, 152, 605, 259 |
| 19 | 57, 689, 152, 121, 259 |
| 3, 689, 8, 121, 259 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 19 x 3 x 689 x 8 x 121 x 259 = 295386371280
Therefore, the lowest common multiple of 855,689,912,605,518 is 295386371280.
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.
855 x 689 x 912 x 605 x 518 = 168370231629600
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
689 : 1, 13, 53, 689
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
605 : 1, 5, 11, 55, 121, 605
518 : 1, 2, 7, 14, 37, 74, 259, 518
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,689,912,605,518, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
689:13x 53
912:2x 2x 2x 2x 3x 19
605:5x 11x 11
518:2x 7x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 19 = 570
Therefore, the value for common factors is 570.
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 = 168370231629600/(1x570)
LCM = 168370231629600/570
LCM = 295386371280
Thus, we can understand that the LCM of 855,689,912,605,518 is 295386371280.
