Find LCM of 912,547,899,688,638 with Prime Factorization
| 2 | 912, 547, 899, 688, 638 |
| 2 | 456, 547, 899, 344, 319 |
| 2 | 228, 547, 899, 172, 319 |
| 2 | 114, 547, 899, 86, 319 |
| 29 | 57, 547, 899, 43, 319 |
| 57, 547, 31, 43, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 29 x 57 x 547 x 31 x 43 x 11 = 212130442128
Therefore, the lowest common multiple of 912,547,899,688,638 is 212130442128.
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.
912 x 547 x 899 x 688 x 638 = 196857050294784
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
547 : 1, 547
899 : 1, 29, 31, 899
688 : 1, 2, 4, 8, 16, 43, 86, 172, 344, 688
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,547,899,688,638, is 1.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
547:547
899:29x 31
688:2x 2x 2x 2x 43
638:2x 11x 29
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 29 = 928
Therefore, the value for common factors is 928.
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 = 196857050294784/(1x928)
LCM = 196857050294784/928
LCM = 212130442128
Thus, we can understand that the LCM of 912,547,899,688,638 is 212130442128.
