Given numbers are 784,140,884,516,246
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 784,140,884,516,246 is 4581966480.
Find LCM of 784,140,884,516,246 with Prime Factorization
| 2 | 784, 140, 884, 516, 246 |
| 2 | 392, 70, 442, 258, 123 |
| 3 | 196, 35, 221, 129, 123 |
| 7 | 196, 35, 221, 43, 41 |
| 28, 5, 221, 43, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 28 x 5 x 221 x 43 x 41 = 4581966480
Therefore, the lowest common multiple of 784,140,884,516,246 is 4581966480.
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 140 x 884 x 516 x 246 = 12316325898240
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
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
516 : 1, 2, 3, 4, 6, 12, 43, 86, 129, 172, 258, 516
246 : 1, 2, 3, 6, 41, 82, 123, 246
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,140,884,516,246, is 2.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
140:2x 2x 5x 7
884:2x 2x 13x 17
516:2x 2x 3x 43
246:2x 3x 41
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 3x 7 = 1344
Therefore, the value for common factors is 1344.
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 = 12316325898240/(2x1344)
LCM = 12316325898240/2688
LCM = 4581966480
Thus, we can understand that the LCM of 784,140,884,516,246 is 4581966480.
