Find LCM of 780,494,108,580,571 with Prime Factorization
| 2 | 780, 494, 108, 580, 571 |
| 2 | 390, 247, 54, 290, 571 |
| 3 | 195, 247, 27, 145, 571 |
| 5 | 65, 247, 9, 145, 571 |
| 13 | 13, 247, 9, 29, 571 |
| 1, 19, 9, 29, 571 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 1 x 19 x 9 x 29 x 571 = 2208639420
Therefore, the lowest common multiple of 780,494,108,580,571 is 2208639420.
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.
780 x 494 x 108 x 580 x 571 = 13781909980800
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.
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
494 : 1, 2, 13, 19, 26, 38, 247, 494
108 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 108
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
571 : 1, 571
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,494,108,580,571, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
494:2x 13x 19
108:2x 2x 3x 3x 3
580:2x 2x 5x 29
571:571
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 5x 13 = 6240
Therefore, the value for common factors is 6240.
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 = 13781909980800/(1x6240)
LCM = 13781909980800/6240
LCM = 2208639420
Thus, we can understand that the LCM of 780,494,108,580,571 is 2208639420.
