Find LCM of 655,820,951,760,786 with Prime Factorization
| 2 | 655, 820, 951, 760, 786 |
| 2 | 655, 410, 951, 380, 393 |
| 3 | 655, 205, 951, 190, 393 |
| 5 | 655, 205, 317, 190, 131 |
| 131 | 131, 41, 317, 38, 131 |
| 1, 41, 317, 38, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 131 x 1 x 41 x 317 x 38 x 1 = 3881943960
Therefore, the lowest common multiple of 655,820,951,760,786 is 3881943960.
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.
655 x 820 x 951 x 760 x 786 = 305120795256000
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.
655 : 1, 5, 131, 655
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
951 : 1, 3, 317, 951
760 : 1, 2, 4, 5, 8, 10, 19, 20, 38, 40, 76, 95, 152, 190, 380, 760
786 : 1, 2, 3, 6, 131, 262, 393, 786
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,820,951,760,786, is 1.
Now, the common factors can be found like this.
655:5x 131
820:2x 2x 5x 41
951:3x 317
760:2x 2x 2x 5x 19
786:2x 3x 131
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 5x 131 = 78600
Therefore, the value for common factors is 78600.
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 = 305120795256000/(1x78600)
LCM = 305120795256000/78600
LCM = 3881943960
Thus, we can understand that the LCM of 655,820,951,760,786 is 3881943960.
