Given numbers are 647,934,894,656
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,934,894,656 is 88599755568.
Find LCM of 647,934,894,656 with Prime Factorization
| 2 | 647, 934, 894, 656 |
| 647, 467, 447, 328 |
Multiply the prime numbers at the bottom and the left side.
2 x 647 x 467 x 447 x 328 = 88599755568
Therefore, the lowest common multiple of 647,934,894,656 is 88599755568.
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.
647 x 934 x 894 x 656 = 354399022272
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.
647 : 1, 647
934 : 1, 2, 467, 934
894 : 1, 2, 3, 6, 149, 298, 447, 894
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,934,894,656, is 1.
Now, the common factors can be found like this.
647:647
934:2x 467
894:2x 3x 149
656:2x 2x 2x 2x 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 2 = 4
Therefore, the value for common factors is 4.
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 = 354399022272/(1x4)
LCM = 354399022272/4
LCM = 88599755568
Thus, we can understand that the LCM of 647,934,894,656 is 88599755568.
