Given numbers are 884,655,917,784
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 884,655,917,784 is 113487920.
Find LCM of 884,655,917,784 with Prime Factorization
| 2 | 884, 655, 917, 784 |
| 2 | 442, 655, 917, 392 |
| 7 | 221, 655, 917, 196 |
| 131 | 221, 655, 131, 28 |
| 221, 5, 1, 28 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 131 x 221 x 5 x 1 x 28 = 113487920
Therefore, the lowest common multiple of 884,655,917,784 is 113487920.
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.
884 x 655 x 917 x 784 = 416273690560
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.
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
655 : 1, 5, 131, 655
917 : 1, 7, 131, 917
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 884,655,917,784, is 1.
Now, the common factors can be found like this.
884:2x 2x 13x 17
655:5x 131
917:7x 131
784:2x 2x 2x 2x 7x 7
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 7x 131 = 3668
Therefore, the value for common factors is 3668.
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 = 416273690560/(1x3668)
LCM = 416273690560/3668
LCM = 113487920
Thus, we can understand that the LCM of 884,655,917,784 is 113487920.
