Find LCM of 547,418,660,780,982 with Prime Factorization
| 2 | 547, 418, 660, 780, 982 |
| 2 | 547, 209, 330, 390, 491 |
| 3 | 547, 209, 165, 195, 491 |
| 5 | 547, 209, 55, 65, 491 |
| 11 | 547, 209, 11, 13, 491 |
| 547, 19, 1, 13, 491 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 547 x 19 x 1 x 13 x 491 = 43783422540
Therefore, the lowest common multiple of 547,418,660,780,982 is 43783422540.
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.
547 x 418 x 660 x 780 x 982 = 115588235505600
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.
547 : 1, 547
418 : 1, 2, 11, 19, 22, 38, 209, 418
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
982 : 1, 2, 491, 982
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 547,418,660,780,982, is 1.
Now, the common factors can be found like this.
547:547
418:2x 11x 19
660:2x 2x 3x 5x 11
780:2x 2x 3x 5x 13
982:2x 491
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 5x 11 = 2640
Therefore, the value for common factors is 2640.
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 = 115588235505600/(1x2640)
LCM = 115588235505600/2640
LCM = 43783422540
Thus, we can understand that the LCM of 547,418,660,780,982 is 43783422540.
