Given numbers are 217,758,583,280
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 217,758,583,280 is 1917906760.
Find LCM of 217,758,583,280 with Prime Factorization
| 2 | 217, 758, 583, 280 |
| 7 | 217, 379, 583, 140 |
| 31, 379, 583, 20 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 31 x 379 x 583 x 20 = 1917906760
Therefore, the lowest common multiple of 217,758,583,280 is 1917906760.
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.
217 x 758 x 583 x 280 = 26850694640
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.
217 : 1, 7, 31, 217
758 : 1, 2, 379, 758
583 : 1, 11, 53, 583
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 217,758,583,280, is 1.
Now, the common factors can be found like this.
217:7x 31
758:2x 379
583:11x 53
280:2x 2x 2x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7 = 14
Therefore, the value for common factors is 14.
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 = 26850694640/(1x14)
LCM = 26850694640/14
LCM = 1917906760
Thus, we can understand that the LCM of 217,758,583,280 is 1917906760.
