The LCM of 543,448,508,280,861 is 6333378240.
Find LCM of 543,448,508,280,861 with Prime Factorization
| 2 | 543, 448, 508, 280, 861 |
| 2 | 543, 224, 254, 140, 861 |
| 2 | 543, 112, 127, 70, 861 |
| 3 | 543, 56, 127, 35, 861 |
| 7 | 181, 56, 127, 35, 287 |
| 181, 8, 127, 5, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 181 x 8 x 127 x 5 x 41 = 6333378240
Therefore, the lowest common multiple of 543,448,508,280,861 is 6333378240.
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.
543 x 448 x 508 x 280 x 861 = 29792211240960
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.
543 : 1, 3, 181, 543
448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448
508 : 1, 2, 4, 127, 254, 508
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 543,448,508,280,861, is 1.
Now, the common factors can be found like this.
543:3x 181
448:2x 2x 2x 2x 2x 2x 7
508:2x 2x 127
280:2x 2x 2x 5x 7
861:3x 7x 41
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 2x 2x 3x 7x 7 = 4704
Therefore, the value for common factors is 4704.
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 = 29792211240960/(1x4704)
LCM = 29792211240960/4704
LCM = 6333378240
Thus, we can understand that the LCM of 543,448,508,280,861 is 6333378240.
