Find LCM of 623,884,156,546,990 with Prime Factorization
| 2 | 623, 884, 156, 546, 990 |
| 2 | 623, 442, 78, 273, 495 |
| 3 | 623, 221, 39, 273, 495 |
| 7 | 623, 221, 13, 91, 165 |
| 13 | 89, 221, 13, 13, 165 |
| 89, 17, 1, 1, 165 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 13 x 89 x 17 x 1 x 1 x 165 = 272612340
Therefore, the lowest common multiple of 623,884,156,546,990 is 272612340.
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.
623 x 884 x 156 x 546 x 990 = 46440057343680
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.
623 : 1, 7, 89, 623
884 : 1, 2, 4, 13, 17, 26, 34, 52, 68, 221, 442, 884
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
546 : 1, 2, 3, 6, 7, 13, 14, 21, 26, 39, 42, 78, 91, 182, 273, 546
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 623,884,156,546,990, is 1.
Now, the common factors can be found like this.
623:7x 89
884:2x 2x 13x 17
156:2x 2x 3x 13
546:2x 3x 7x 13
990:2x 3x 3x 5x 11
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 7x 13x 13 = 170352
Therefore, the value for common factors is 170352.
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 = 46440057343680/(1x170352)
LCM = 46440057343680/170352
LCM = 272612340
Thus, we can understand that the LCM of 623,884,156,546,990 is 272612340.
