Given numbers are 626,804,391,460
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 626,804,391,460 is 491979660.
Find LCM of 626,804,391,460 with Prime Factorization
| 2 | 626, 804, 391, 460 |
| 2 | 313, 402, 391, 230 |
| 23 | 313, 201, 391, 115 |
| 313, 201, 17, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 23 x 313 x 201 x 17 x 5 = 491979660
Therefore, the lowest common multiple of 626,804,391,460 is 491979660.
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.
626 x 804 x 391 x 460 = 90524257440
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.
626 : 1, 2, 313, 626
804 : 1, 2, 3, 4, 6, 12, 67, 134, 201, 268, 402, 804
391 : 1, 17, 23, 391
460 : 1, 2, 4, 5, 10, 20, 23, 46, 92, 115, 230, 460
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 626,804,391,460, is 1.
Now, the common factors can be found like this.
626:2x 313
804:2x 2x 3x 67
391:17x 23
460:2x 2x 5x 23
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 23 = 184
Therefore, the value for common factors is 184.
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 = 90524257440/(1x184)
LCM = 90524257440/184
LCM = 491979660
Thus, we can understand that the LCM of 626,804,391,460 is 491979660.
