Find LCM of 430,454,783,990,946 with Prime Factorization
| 2 | 430, 454, 783, 990, 946 |
| 3 | 215, 227, 783, 495, 473 |
| 3 | 215, 227, 261, 165, 473 |
| 5 | 215, 227, 87, 55, 473 |
| 11 | 43, 227, 87, 11, 473 |
| 43 | 43, 227, 87, 1, 43 |
| 1, 227, 87, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 11 x 43 x 1 x 227 x 87 x 1 x 1 = 840714930
Therefore, the lowest common multiple of 430,454,783,990,946 is 840714930.
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.
430 x 454 x 783 x 990 x 946 = 143156938280400
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.
430 : 1, 2, 5, 10, 43, 86, 215, 430
454 : 1, 2, 227, 454
783 : 1, 3, 9, 27, 29, 87, 261, 783
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
946 : 1, 2, 11, 22, 43, 86, 473, 946
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,454,783,990,946, is 1.
Now, the common factors can be found like this.
430:2x 5x 43
454:2x 227
783:3x 3x 3x 29
990:2x 3x 3x 5x 11
946:2x 11x 43
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 3x 5x 11x 43 = 170280
Therefore, the value for common factors is 170280.
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 = 143156938280400/(1x170280)
LCM = 143156938280400/170280
LCM = 840714930
Thus, we can understand that the LCM of 430,454,783,990,946 is 840714930.
