Given numbers are 840,776,881,776
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 840,776,881,776 is 71783880.
Find LCM of 840,776,881,776 with Prime Factorization
| 2 | 840, 776, 881, 776 |
| 2 | 420, 388, 881, 388 |
| 2 | 210, 194, 881, 194 |
| 97 | 105, 97, 881, 97 |
| 105, 1, 881, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 97 x 105 x 1 x 881 x 1 = 71783880
Therefore, the lowest common multiple of 840,776,881,776 is 71783880.
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 776 x 881 x 776 = 445634327040
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
776 : 1, 2, 4, 8, 97, 194, 388, 776
881 : 1, 881
776 : 1, 2, 4, 8, 97, 194, 388, 776
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,776,881,776, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
776:2x 2x 2x 97
881:881
776:2x 2x 2x 97
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 2x 97 = 6208
Therefore, the value for common factors is 6208.
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 = 445634327040/(1x6208)
LCM = 445634327040/6208
LCM = 71783880
Thus, we can understand that the LCM of 840,776,881,776 is 71783880.
