Given numbers are 910,703,840,423
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 910,703,840,423 is 1082423160.
Find LCM of 910,703,840,423 with Prime Factorization
| 2 | 910, 703, 840, 423 |
| 3 | 455, 703, 420, 423 |
| 5 | 455, 703, 140, 141 |
| 7 | 91, 703, 28, 141 |
| 13, 703, 4, 141 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 13 x 703 x 4 x 141 = 1082423160
Therefore, the lowest common multiple of 910,703,840,423 is 1082423160.
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.
910 x 703 x 840 x 423 = 227308863600
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.
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
703 : 1, 19, 37, 703
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
423 : 1, 3, 9, 47, 141, 423
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 910,703,840,423, is 1.
Now, the common factors can be found like this.
910:2x 5x 7x 13
703:19x 37
840:2x 2x 2x 3x 5x 7
423:3x 3x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 227308863600/(1x210)
LCM = 227308863600/210
LCM = 1082423160
Thus, we can understand that the LCM of 910,703,840,423 is 1082423160.
