Given numbers are 917,655,185,864,487
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 917,655,185,864,487 is 71381187360.
Find LCM of 917,655,185,864,487 with Prime Factorization
| 5 | 917, 655, 185, 864, 487 |
| 131 | 917, 131, 37, 864, 487 |
| 7, 1, 37, 864, 487 |
Multiply the prime numbers at the bottom and the left side.
5 x 131 x 7 x 1 x 37 x 864 x 487 = 71381187360
Therefore, the lowest common multiple of 917,655,185,864,487 is 71381187360.
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.
917 x 655 x 185 x 864 x 487 = 46754677720800
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.
917 : 1, 7, 131, 917
655 : 1, 5, 131, 655
185 : 1, 5, 37, 185
864 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 27, 32, 36, 48, 54, 72, 96, 108, 144, 216, 288, 432, 864
487 : 1, 487
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 917,655,185,864,487, is 1.
Now, the common factors can be found like this.
917:7x 131
655:5x 131
185:5x 37
864:2x 2x 2x 2x 2x 3x 3x 3
487:487
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 131 = 655
Therefore, the value for common factors is 655.
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 = 46754677720800/(1x655)
LCM = 46754677720800/655
LCM = 71381187360
Thus, we can understand that the LCM of 917,655,185,864,487 is 71381187360.
