Find LCM of 663,867,820,607,780 with Prime Factorization
| 2 | 663, 867, 820, 607, 780 |
| 2 | 663, 867, 410, 607, 390 |
| 3 | 663, 867, 205, 607, 195 |
| 5 | 221, 289, 205, 607, 65 |
| 13 | 221, 289, 41, 607, 13 |
| 17 | 17, 289, 41, 607, 1 |
| 1, 17, 41, 607, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 13 x 17 x 1 x 17 x 41 x 607 x 1 = 5610027540
Therefore, the lowest common multiple of 663,867,820,607,780 is 5610027540.
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.
663 x 867 x 820 x 607 x 780 = 223166895541200
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.
663 : 1, 3, 13, 17, 39, 51, 221, 663
867 : 1, 3, 17, 51, 289, 867
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
607 : 1, 607
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,867,820,607,780, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
867:3x 17x 17
820:2x 2x 5x 41
607:607
780:2x 2x 3x 5x 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 2x 3x 3x 5x 13x 17 = 39780
Therefore, the value for common factors is 39780.
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 = 223166895541200/(1x39780)
LCM = 223166895541200/39780
LCM = 5610027540
Thus, we can understand that the LCM of 663,867,820,607,780 is 5610027540.
