Find LCM of 784,473,975,728,255 with Prime Factorization
| 2 | 784, 473, 975, 728, 255 |
| 2 | 392, 473, 975, 364, 255 |
| 2 | 196, 473, 975, 182, 255 |
| 3 | 98, 473, 975, 91, 255 |
| 5 | 98, 473, 325, 91, 85 |

| 13 | 14, 473, 65, 13, 17 |
| 14, 473, 5, 1, 17 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 13 x 14 x 473 x 5 x 1 x 17 = 6146540400
Therefore, the lowest common multiple of 784,473,975,728,255 is 6146540400.
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.
784 x 473 x 975 x 728 x 255 = 67120221168000
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.
784 : 1, 2, 4, 7, 8, 14, 16, 28, 49, 56, 98, 112, 196, 392, 784
473 : 1, 11, 43, 473
975 : 1, 3, 5, 13, 15, 25, 39, 65, 75, 195, 325, 975
728 : 1, 2, 4, 7, 8, 13, 14, 26, 28, 52, 56, 91, 104, 182, 364, 728
255 : 1, 3, 5, 15, 17, 51, 85, 255
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 784,473,975,728,255, is 1.
Now, the common factors can be found like this.
784:2x 2x 2x 2x 7x 7
473:11x 43
975:3x 5x 5x 13
728:2x 2x 2x 7x 13
255:3x 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 3x 5x 7x 13 = 10920
Therefore, the value for common factors is 10920.
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 = 67120221168000/(1x10920)
LCM = 67120221168000/10920
LCM = 6146540400
Thus, we can understand that the LCM of 784,473,975,728,255 is 6146540400.
