Find LCM of 684,523,570,990,340 with Prime Factorization
| 2 | 684, 523, 570, 990, 340 |
| 2 | 342, 523, 285, 495, 170 |
| 3 | 171, 523, 285, 495, 85 |
| 3 | 57, 523, 95, 165, 85 |
| 5 | 19, 523, 95, 55, 85 |
| 19 | 19, 523, 19, 11, 17 |
| 1, 523, 1, 11, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 5 x 19 x 1 x 523 x 1 x 11 x 17 = 334479420
Therefore, the lowest common multiple of 684,523,570,990,340 is 334479420.
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.
684 x 523 x 570 x 990 x 340 = 68635176984000
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
523 : 1, 523
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
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
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,523,570,990,340, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
523:523
570:2x 3x 5x 19
990:2x 3x 3x 5x 11
340:2x 2x 5x 17
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 3x 5x 5x 19 = 205200
Therefore, the value for common factors is 205200.
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 = 68635176984000/(1x205200)
LCM = 68635176984000/205200
LCM = 334479420
Thus, we can understand that the LCM of 684,523,570,990,340 is 334479420.
