Given numbers are 784,811,609,923,402
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,811,609,923,402 is 3420839302608.
Find LCM of 784,811,609,923,402 with Prime Factorization
| 2 | 784, 811, 609, 923, 402 |
| 3 | 392, 811, 609, 923, 201 |
| 7 | 392, 811, 203, 923, 67 |
| 56, 811, 29, 923, 67 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 56 x 811 x 29 x 923 x 67 = 3420839302608
Therefore, the lowest common multiple of 784,811,609,923,402 is 3420839302608.
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.
784 x 811 x 609 x 923 x 402 = 143675250709536
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
811 : 1, 811
609 : 1, 3, 7, 21, 29, 87, 203, 609
923 : 1, 13, 71, 923
402 : 1, 2, 3, 6, 67, 134, 201, 402
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,811,609,923,402, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
811:811
609:3x 7x 29
923:13x 71
402:2x 3x 67
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 7 = 42
Therefore, the value for common factors is 42.
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 = 143675250709536/(1x42)
LCM = 143675250709536/42
LCM = 3420839302608
Thus, we can understand that the LCM of 784,811,609,923,402 is 3420839302608.
