The LCM of 476,935,878,840 is 68958120.
Find LCM of 476,935,878,840 with Prime Factorization
| 2 | 476, 935, 878, 840 |
| 2 | 238, 935, 439, 420 |
| 5 | 119, 935, 439, 210 |
| 7 | 119, 187, 439, 42 |
| 17 | 17, 187, 439, 6 |
| 1, 11, 439, 6 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 17 x 1 x 11 x 439 x 6 = 68958120
Therefore, the lowest common multiple of 476,935,878,840 is 68958120.
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.
476 x 935 x 878 x 840 = 328240651200
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.
476 : 1, 2, 4, 7, 14, 17, 28, 34, 68, 119, 238, 476
935 : 1, 5, 11, 17, 55, 85, 187, 935
878 : 1, 2, 439, 878
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 476,935,878,840, is 1.
Now, the common factors can be found like this.
476:2x 2x 7x 17
935:5x 11x 17
878:2x 439
840:2x 2x 2x 3x 5x 7
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 5x 7x 17 = 4760
Therefore, the value for common factors is 4760.
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 = 328240651200/(1x4760)
LCM = 328240651200/4760
LCM = 68958120
Thus, we can understand that the LCM of 476,935,878,840 is 68958120.
