Find LCM of 643,960,594,375,781 with Prime Factorization
| 2 | 643, 960, 594, 375, 781 |
| 3 | 643, 480, 297, 375, 781 |
| 5 | 643, 160, 99, 125, 781 |
| 11 | 643, 32, 99, 25, 781 |
| 643, 32, 9, 25, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 643 x 32 x 9 x 25 x 71 = 108471528000
Therefore, the lowest common multiple of 643,960,594,375,781 is 108471528000.
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.
643 x 960 x 594 x 375 x 781 = 107386812720000
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.
643 : 1, 643
960 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 64, 80, 96, 120, 160, 192, 240, 320, 480, 960
594 : 1, 2, 3, 6, 9, 11, 18, 22, 27, 33, 54, 66, 99, 198, 297, 594
375 : 1, 3, 5, 15, 25, 75, 125, 375
781 : 1, 11, 71, 781
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 643,960,594,375,781, is 1.
Now, the common factors can be found like this.
643:643
960:2x 2x 2x 2x 2x 2x 3x 5
594:2x 3x 3x 3x 11
375:3x 5x 5x 5
781:11x 71
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5x 11 = 990
Therefore, the value for common factors is 990.
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 = 107386812720000/(1x990)
LCM = 107386812720000/990
LCM = 108471528000
Thus, we can understand that the LCM of 643,960,594,375,781 is 108471528000.
