Find LCM of 280,474,554,840,156 with Prime Factorization
| 2 | 280, 474, 554, 840, 156 |
| 2 | 140, 237, 277, 420, 78 |
| 2 | 70, 237, 277, 210, 39 |
| 3 | 35, 237, 277, 105, 39 |
| 5 | 35, 79, 277, 35, 13 |
| 7 | 7, 79, 277, 7, 13 |
| 1, 79, 277, 1, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 1 x 79 x 277 x 1 x 13 = 238962360
Therefore, the lowest common multiple of 280,474,554,840,156 is 238962360.
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.
280 x 474 x 554 x 840 x 156 = 9634962355200
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.
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
474 : 1, 2, 3, 6, 79, 158, 237, 474
554 : 1, 2, 277, 554
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,474,554,840,156, is 2.
Now, the common factors can be found like this.
280:2x 2x 2x 5x 7
474:2x 3x 79
554:2x 277
840:2x 2x 2x 3x 5x 7
156:2x 2x 3x 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 2x 2x 2x 2x 3x 3x 5x 7 = 20160
Therefore, the value for common factors is 20160.
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 = 9634962355200/(2x20160)
LCM = 9634962355200/40320
LCM = 238962360
Thus, we can understand that the LCM of 280,474,554,840,156 is 238962360.
