Find LCM of 649,344,780,561,509 with Prime Factorization
| 2 | 649, 344, 780, 561, 509 |
| 2 | 649, 172, 390, 561, 509 |
| 3 | 649, 86, 195, 561, 509 |
| 11 | 649, 86, 65, 187, 509 |
| 59, 86, 65, 17, 509 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 59 x 86 x 65 x 17 x 509 = 376707662760
Therefore, the lowest common multiple of 649,344,780,561,509 is 376707662760.
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.
649 x 344 x 780 x 561 x 509 = 49725411484320
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.
649 : 1, 11, 59, 649
344 : 1, 2, 4, 8, 43, 86, 172, 344
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
561 : 1, 3, 11, 17, 33, 51, 187, 561
509 : 1, 509
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 649,344,780,561,509, is 1.
Now, the common factors can be found like this.
649:11x 59
344:2x 2x 2x 43
780:2x 2x 3x 5x 13
561:3x 11x 17
509:509
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 11 = 132
Therefore, the value for common factors is 132.
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 = 49725411484320/(1x132)
LCM = 49725411484320/132
LCM = 376707662760
Thus, we can understand that the LCM of 649,344,780,561,509 is 376707662760.
