The LCM of 918,782,494,390 is 26075790.
Find LCM of 918,782,494,390 with Prime Factorization
| 2 | 918, 782, 494, 390 |
| 3 | 459, 391, 247, 195 |
| 13 | 153, 391, 247, 65 |
| 17 | 153, 391, 19, 5 |
| 9, 23, 19, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 17 x 9 x 23 x 19 x 5 = 26075790
Therefore, the lowest common multiple of 918,782,494,390 is 26075790.
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.
918 x 782 x 494 x 390 = 138305990160
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.
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
782 : 1, 2, 17, 23, 34, 46, 391, 782
494 : 1, 2, 13, 19, 26, 38, 247, 494
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 918,782,494,390, is 2.
Now, the common factors can be found like this.
918:2x 3x 3x 3x 17
782:2x 17x 23
494:2x 13x 19
390:2x 3x 5x 13
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 3x 13x 17 = 2652
Therefore, the value for common factors is 2652.
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 = 138305990160/(2x2652)
LCM = 138305990160/5304
LCM = 26075790
Thus, we can understand that the LCM of 918,782,494,390 is 26075790.
