Given numbers are 578,559,355,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,559,355,390 is 344103630.
Find LCM of 578,559,355,390 with Prime Factorization
| 2 | 578, 559, 355, 390 |
| 5 | 289, 559, 355, 195 |
| 13 | 289, 559, 71, 39 |
| 289, 43, 71, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 289 x 43 x 71 x 3 = 344103630
Therefore, the lowest common multiple of 578,559,355,390 is 344103630.
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.
578 x 559 x 355 x 390 = 44733471900
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.
578 : 1, 2, 17, 34, 289, 578
559 : 1, 13, 43, 559
355 : 1, 5, 71, 355
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,559,355,390, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
559:13x 43
355:5x 71
390:2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 44733471900/(1x130)
LCM = 44733471900/130
LCM = 344103630
Thus, we can understand that the LCM of 578,559,355,390 is 344103630.
