The LCM of 437,820,920,781 is 559727080.
Find LCM of 437,820,920,781 with Prime Factorization
| 2 | 437, 820, 920, 781 |
| 2 | 437, 410, 460, 781 |
| 5 | 437, 205, 230, 781 |
| 23 | 437, 41, 46, 781 |
| 19, 41, 2, 781 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 23 x 19 x 41 x 2 x 781 = 559727080
Therefore, the lowest common multiple of 437,820,920,781 is 559727080.
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.
437 x 820 x 920 x 781 = 257474456800
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.
437 : 1, 19, 23, 437
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
920 : 1, 2, 4, 5, 8, 10, 20, 23, 40, 46, 92, 115, 184, 230, 460, 920
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,820,920,781, is 1.
Now, the common factors can be found like this.
437:19x 23
820:2x 2x 5x 41
920:2x 2x 2x 5x 23
781:11x 71
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 5x 23 = 460
Therefore, the value for common factors is 460.
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 = 257474456800/(1x460)
LCM = 257474456800/460
LCM = 559727080
Thus, we can understand that the LCM of 437,820,920,781 is 559727080.
