The LCM of 451,689,786,660,779 is 46405762260.
Find LCM of 451,689,786,660,779 with Prime Factorization
| 2 | 451, 689, 786, 660, 779 |
| 3 | 451, 689, 393, 330, 779 |
| 11 | 451, 689, 131, 110, 779 |
| 41 | 41, 689, 131, 10, 779 |
| 1, 689, 131, 10, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 11 x 41 x 1 x 689 x 131 x 10 x 19 = 46405762260
Therefore, the lowest common multiple of 451,689,786,660,779 is 46405762260.
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.
451 x 689 x 786 x 660 x 779 = 125573992675560
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.
451 : 1, 11, 41, 451
689 : 1, 13, 53, 689
786 : 1, 2, 3, 6, 131, 262, 393, 786
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 451,689,786,660,779, is 1.
Now, the common factors can be found like this.
451:11x 41
689:13x 53
786:2x 3x 131
660:2x 2x 3x 5x 11
779:19x 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 3x 11x 41 = 2706
Therefore, the value for common factors is 2706.
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 = 125573992675560/(1x2706)
LCM = 125573992675560/2706
LCM = 46405762260
Thus, we can understand that the LCM of 451,689,786,660,779 is 46405762260.
