The LCM of 514,689,840,624 is 297482640.
Find LCM of 514,689,840,624 with Prime Factorization
| 2 | 514, 689, 840, 624 |
| 2 | 257, 689, 420, 312 |
| 2 | 257, 689, 210, 156 |
| 3 | 257, 689, 105, 78 |
| 13 | 257, 689, 35, 26 |
| 257, 53, 35, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 13 x 257 x 53 x 35 x 2 = 297482640
Therefore, the lowest common multiple of 514,689,840,624 is 297482640.
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.
514 x 689 x 840 x 624 = 185629167360
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.
514 : 1, 2, 257, 514
689 : 1, 13, 53, 689
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 514,689,840,624, is 1.
Now, the common factors can be found like this.
514:2x 257
689:13x 53
840:2x 2x 2x 3x 5x 7
624:2x 2x 2x 2x 3x 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 2x 2x 2x 3x 13 = 624
Therefore, the value for common factors is 624.
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 = 185629167360/(1x624)
LCM = 185629167360/624
LCM = 297482640
Thus, we can understand that the LCM of 514,689,840,624 is 297482640.
