Find LCM of 855,638,660,913,736 with Prime Factorization
| 2 | 855, 638, 660, 913, 736 |
| 2 | 855, 319, 330, 913, 368 |
| 3 | 855, 319, 165, 913, 184 |
| 5 | 285, 319, 55, 913, 184 |
| 11 | 57, 319, 11, 913, 184 |
| 57, 29, 1, 83, 184 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 57 x 29 x 1 x 83 x 184 = 16661446560
Therefore, the lowest common multiple of 855,638,660,913,736 is 16661446560.
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.
855 x 638 x 660 x 913 x 736 = 241924204051200
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
638 : 1, 2, 11, 22, 29, 58, 319, 638
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
913 : 1, 11, 83, 913
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,638,660,913,736, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
638:2x 11x 29
660:2x 2x 3x 5x 11
913:11x 83
736:2x 2x 2x 2x 2x 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 3x 5x 11x 11 = 14520
Therefore, the value for common factors is 14520.
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 = 241924204051200/(1x14520)
LCM = 241924204051200/14520
LCM = 16661446560
Thus, we can understand that the LCM of 855,638,660,913,736 is 16661446560.
