Given numbers are 615,421,870,624,718
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 615,421,870,624,718 is 560677325520.
Find LCM of 615,421,870,624,718 with Prime Factorization
| 2 | 615, 421, 870, 624, 718 |
| 3 | 615, 421, 435, 312, 359 |
| 5 | 205, 421, 145, 104, 359 |
| 41, 421, 29, 104, 359 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 41 x 421 x 29 x 104 x 359 = 560677325520
Therefore, the lowest common multiple of 615,421,870,624,718 is 560677325520.
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.
615 x 421 x 870 x 624 x 718 = 100921918593600
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
421 : 1, 421
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
718 : 1, 2, 359, 718
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,421,870,624,718, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
421:421
870:2x 3x 5x 29
624:2x 2x 2x 2x 3x 13
718:2x 359
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 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 100921918593600/(1x180)
LCM = 100921918593600/180
LCM = 560677325520
Thus, we can understand that the LCM of 615,421,870,624,718 is 560677325520.
