| 5 | 205, 20, 299, 43, 709 |
| 41, 4, 299, 43, 709 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 5 x 41 x 4 x 299 x 43 x 709 = 358790527680
Therefore, the lowest common multiple of 615,960,299,688,709 is 358790527680.
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.
615 x 960 x 299 x 688 x 709 = 86109726643200
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.
615 : 1, 3, 5, 15, 41, 123, 205, 615
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
299 : 1, 13, 23, 299
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
709 : 1, 709
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 615,960,299,688,709, is 1.
Now, the common factors can be found like this.
615:3x 5x 41
960:2x 2x 2x 2x 2x 2x 3x 5
299:13x 23
688:2x 2x 2x 2x 43
709:709
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 3x 5 = 240
Therefore, the value for common factors is 240.
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 = 86109726643200/(1x240)
LCM = 86109726643200/240
LCM = 358790527680
Thus, we can understand that the LCM of 615,960,299,688,709 is 358790527680.
