Find LCM of 994,840,238,867,746 with Prime Factorization
| 2 | 994, 840, 238, 867, 746 |
| 3 | 497, 420, 119, 867, 373 |
| 7 | 497, 140, 119, 289, 373 |
| 17 | 71, 20, 17, 289, 373 |
| 71, 20, 1, 17, 373 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 17 x 71 x 20 x 1 x 17 x 373 = 6429013080
Therefore, the lowest common multiple of 994,840,238,867,746 is 6429013080.
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.
994 x 840 x 238 x 867 x 746 = 128528829495360
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.
994 : 1, 2, 7, 14, 71, 142, 497, 994
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
238 : 1, 2, 7, 14, 17, 34, 119, 238
867 : 1, 3, 17, 51, 289, 867
746 : 1, 2, 373, 746
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 994,840,238,867,746, is 1.
Now, the common factors can be found like this.
994:2x 7x 71
840:2x 2x 2x 3x 5x 7
238:2x 7x 17
867:3x 17x 17
746:2x 373
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 7x 7x 17 = 19992
Therefore, the value for common factors is 19992.
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 = 128528829495360/(1x19992)
LCM = 128528829495360/19992
LCM = 6429013080
Thus, we can understand that the LCM of 994,840,238,867,746 is 6429013080.
