Given numbers are 504,780,806,649
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 504,780,806,649 is 659098440.
Find LCM of 504,780,806,649 with Prime Factorization
| 2 | 504, 780, 806, 649 |
| 2 | 252, 390, 403, 649 |
| 3 | 126, 195, 403, 649 |
| 13 | 42, 65, 403, 649 |
| 42, 5, 31, 649 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 13 x 42 x 5 x 31 x 649 = 659098440
Therefore, the lowest common multiple of 504,780,806,649 is 659098440.
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.
504 x 780 x 806 x 649 = 205638713280
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.
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
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
806 : 1, 2, 13, 26, 31, 62, 403, 806
649 : 1, 11, 59, 649
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 504,780,806,649, is 1.
Now, the common factors can be found like this.
504:2x 2x 2x 3x 3x 7
780:2x 2x 3x 5x 13
806:2x 13x 31
649:11x 59
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 3x 13 = 312
Therefore, the value for common factors is 312.
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 = 205638713280/(1x312)
LCM = 205638713280/312
LCM = 659098440
Thus, we can understand that the LCM of 504,780,806,649 is 659098440.
