Find LCM of 628,520,689,371,867 with Prime Factorization
| 2 | 628, 520, 689, 371, 867 |
| 2 | 314, 260, 689, 371, 867 |
| 13 | 157, 130, 689, 371, 867 |
| 53 | 157, 10, 53, 371, 867 |
| 157, 10, 1, 7, 867 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 53 x 157 x 10 x 1 x 7 x 867 = 26260077480
Therefore, the lowest common multiple of 628,520,689,371,867 is 26260077480.
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.
628 x 520 x 689 x 371 x 867 = 72372773534880
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.
628 : 1, 2, 4, 157, 314, 628
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
689 : 1, 13, 53, 689
371 : 1, 7, 53, 371
867 : 1, 3, 17, 51, 289, 867
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,520,689,371,867, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
520:2x 2x 2x 5x 13
689:13x 53
371:7x 53
867:3x 17x 17
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 13x 53 = 2756
Therefore, the value for common factors is 2756.
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 = 72372773534880/(1x2756)
LCM = 72372773534880/2756
LCM = 26260077480
Thus, we can understand that the LCM of 628,520,689,371,867 is 26260077480.
