Find LCM of 560,646,540,963,418 with Prime Factorization
| 2 | 560, 646, 540, 963, 418 |
| 2 | 280, 323, 270, 963, 209 |
| 3 | 140, 323, 135, 963, 209 |
| 3 | 140, 323, 45, 321, 209 |
| 5 | 140, 323, 15, 107, 209 |
| 19 | 28, 323, 3, 107, 209 |
| 28, 17, 3, 107, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 19 x 28 x 17 x 3 x 107 x 11 = 5748185520
Therefore, the lowest common multiple of 560,646,540,963,418 is 5748185520.
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.
560 x 646 x 540 x 963 x 418 = 78635177913600
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.
560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560
646 : 1, 2, 17, 19, 34, 38, 323, 646
540 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 27, 30, 36, 45, 54, 60, 90, 108, 135, 180, 270, 540
963 : 1, 3, 9, 107, 321, 963
418 : 1, 2, 11, 19, 22, 38, 209, 418
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 560,646,540,963,418, is 1.
Now, the common factors can be found like this.
560:2x 2x 2x 2x 5x 7
646:2x 17x 19
540:2x 2x 3x 3x 3x 5
963:3x 3x 107
418:2x 11x 19
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 5x 19 = 13680
Therefore, the value for common factors is 13680.
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 = 78635177913600/(1x13680)
LCM = 78635177913600/13680
LCM = 5748185520
Thus, we can understand that the LCM of 560,646,540,963,418 is 5748185520.
