Given numbers are 621,718,845,910
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 621,718,845,910 is 2637368370.
Find LCM of 621,718,845,910 with Prime Factorization
| 2 | 621, 718, 845, 910 |
| 5 | 621, 359, 845, 455 |
| 13 | 621, 359, 169, 91 |
| 621, 359, 13, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 621 x 359 x 13 x 7 = 2637368370
Therefore, the lowest common multiple of 621,718,845,910 is 2637368370.
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.
621 x 718 x 845 x 910 = 342857888100
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.
621 : 1, 3, 9, 23, 27, 69, 207, 621
718 : 1, 2, 359, 718
845 : 1, 5, 13, 65, 169, 845
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 621,718,845,910, is 1.
Now, the common factors can be found like this.
621:3x 3x 3x 23
718:2x 359
845:5x 13x 13
910:2x 5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 342857888100/(1x130)
LCM = 342857888100/130
LCM = 2637368370
Thus, we can understand that the LCM of 621,718,845,910 is 2637368370.
