| 11 | 517, 11, 10, 473, 357 |
| 47, 1, 10, 43, 357 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 2 x 11 x 47 x 1 x 10 x 43 x 357 = 5079338880
Therefore, the lowest common multiple of 517,704,640,946,357 is 5079338880.
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.
517 x 704 x 640 x 946 x 357 = 78668800573440
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.
517 : 1, 11, 47, 517
704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
946 : 1, 2, 11, 22, 43, 86, 473, 946
357 : 1, 3, 7, 17, 21, 51, 119, 357
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 517,704,640,946,357, is 1.
Now, the common factors can be found like this.
517:11x 47
704:2x 2x 2x 2x 2x 2x 11
640:2x 2x 2x 2x 2x 2x 2x 5
946:2x 11x 43
357:3x 7x 17
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 2x 11x 11 = 15488
Therefore, the value for common factors is 15488.
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 = 78668800573440/(1x15488)
LCM = 78668800573440/15488
LCM = 5079338880
Thus, we can understand that the LCM of 517,704,640,946,357 is 5079338880.
