The LCM of 459,642,784,280 is 192522960.
Find LCM of 459,642,784,280 with Prime Factorization
| 2 | 459, 642, 784, 280 |
| 2 | 459, 321, 392, 140 |
| 2 | 459, 321, 196, 70 |
| 3 | 459, 321, 98, 35 |
| 7 | 153, 107, 98, 35 |
| 153, 107, 14, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 7 x 153 x 107 x 14 x 5 = 192522960
Therefore, the lowest common multiple of 459,642,784,280 is 192522960.
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.
459 x 642 x 784 x 280 = 64687714560
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.
459 : 1, 3, 9, 17, 27, 51, 153, 459
642 : 1, 2, 3, 6, 107, 214, 321, 642
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 459,642,784,280, is 1.
Now, the common factors can be found like this.
459:3x 3x 3x 17
642:2x 3x 107
784:2x 2x 2x 2x 7x 7
280:2x 2x 2x 5x 7
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 7 = 336
Therefore, the value for common factors is 336.
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 = 64687714560/(1x336)
LCM = 64687714560/336
LCM = 192522960
Thus, we can understand that the LCM of 459,642,784,280 is 192522960.
