Given numbers are 840,712,845,596
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 840,712,845,596 is 1882531560.
Find LCM of 840,712,845,596 with Prime Factorization
| 2 | 840, 712, 845, 596 |
| 2 | 420, 356, 845, 298 |
| 2 | 210, 178, 845, 149 |
| 5 | 105, 89, 845, 149 |
| 21, 89, 169, 149 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 21 x 89 x 169 x 149 = 1882531560
Therefore, the lowest common multiple of 840,712,845,596 is 1882531560.
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.
840 x 712 x 845 x 596 = 301205049600
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.
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
712 : 1, 2, 4, 8, 89, 178, 356, 712
845 : 1, 5, 13, 65, 169, 845
596 : 1, 2, 4, 149, 298, 596
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,712,845,596, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
712:2x 2x 2x 89
845:5x 13x 13
596:2x 2x 149
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 2x 2x 5 = 160
Therefore, the value for common factors is 160.
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 = 301205049600/(1x160)
LCM = 301205049600/160
LCM = 1882531560
Thus, we can understand that the LCM of 840,712,845,596 is 1882531560.
