Find LCM of 938,871,374,840,391 with Prime Factorization
| 2 | 938, 871, 374, 840, 391 |
| 7 | 469, 871, 187, 420, 391 |
| 17 | 67, 871, 187, 60, 391 |
| 67 | 67, 871, 11, 60, 23 |
| 1, 13, 11, 60, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 17 x 67 x 1 x 13 x 11 x 60 x 23 = 3146783640
Therefore, the lowest common multiple of 938,871,374,840,391 is 3146783640.
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.
938 x 871 x 374 x 840 x 391 = 100357223846880
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.
938 : 1, 2, 7, 14, 67, 134, 469, 938
871 : 1, 13, 67, 871
374 : 1, 2, 11, 17, 22, 34, 187, 374
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
391 : 1, 17, 23, 391
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 938,871,374,840,391, is 1.
Now, the common factors can be found like this.
938:2x 7x 67
871:13x 67
374:2x 11x 17
840:2x 2x 2x 3x 5x 7
391:17x 23
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 7x 17x 67 = 31892
Therefore, the value for common factors is 31892.
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 = 100357223846880/(1x31892)
LCM = 100357223846880/31892
LCM = 3146783640
Thus, we can understand that the LCM of 938,871,374,840,391 is 3146783640.
