Find LCM of 671,306,720,379,648 with Prime Factorization
| 2 | 671, 306, 720, 379, 648 |
| 2 | 671, 153, 360, 379, 324 |
| 2 | 671, 153, 180, 379, 162 |
| 3 | 671, 153, 90, 379, 81 |
| 3 | 671, 51, 30, 379, 27 |
| 671, 17, 10, 379, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 3 x 671 x 17 x 10 x 379 x 9 = 28014679440
Therefore, the lowest common multiple of 671,306,720,379,648 is 28014679440.
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.
671 x 306 x 720 x 379 x 648 = 36307024554240
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.
671 : 1, 11, 61, 671
306 : 1, 2, 3, 6, 9, 17, 18, 34, 51, 102, 153, 306
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
379 : 1, 379
648 : 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 27, 36, 54, 72, 81, 108, 162, 216, 324, 648
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,306,720,379,648, is 1.
Now, the common factors can be found like this.
671:11x 61
306:2x 3x 3x 17
720:2x 2x 2x 2x 3x 3x 5
379:379
648:2x 2x 2x 3x 3x 3x 3
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 2x 3x 3x 3x 3 = 1296
Therefore, the value for common factors is 1296.
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 = 36307024554240/(1x1296)
LCM = 36307024554240/1296
LCM = 28014679440
Thus, we can understand that the LCM of 671,306,720,379,648 is 28014679440.
