Find LCM of 390,424,440,581,308 with Prime Factorization
| 2 | 390, 424, 440, 581, 308 |
| 2 | 195, 212, 220, 581, 154 |
| 2 | 195, 106, 110, 581, 77 |
| 5 | 195, 53, 55, 581, 77 |
| 7 | 39, 53, 11, 581, 77 |
| 11 | 39, 53, 11, 83, 11 |
| 39, 53, 1, 83, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 7 x 11 x 39 x 53 x 1 x 83 x 1 = 528407880
Therefore, the lowest common multiple of 390,424,440,581,308 is 528407880.
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.
390 x 424 x 440 x 581 x 308 = 13019970163200
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.
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
424 : 1, 2, 4, 8, 53, 106, 212, 424
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
581 : 1, 7, 83, 581
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,424,440,581,308, is 1.
Now, the common factors can be found like this.
390:2x 3x 5x 13
424:2x 2x 2x 53
440:2x 2x 2x 5x 11
581:7x 83
308:2x 2x 7x 11
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 2x 5x 7x 11 = 24640
Therefore, the value for common factors is 24640.
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 = 13019970163200/(1x24640)
LCM = 13019970163200/24640
LCM = 528407880
Thus, we can understand that the LCM of 390,424,440,581,308 is 528407880.
