Given numbers are 285,392,718,969,802
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 285,392,718,969,802 is 273412691160.
Find LCM of 285,392,718,969,802 with Prime Factorization
| 2 | 285, 392, 718, 969, 802 |
| 3 | 285, 196, 359, 969, 401 |
| 19 | 95, 196, 359, 323, 401 |
| 5, 196, 359, 17, 401 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 5 x 196 x 359 x 17 x 401 = 273412691160
Therefore, the lowest common multiple of 285,392,718,969,802 is 273412691160.
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.
285 x 392 x 718 x 969 x 802 = 62338093584480
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.
285 : 1, 3, 5, 15, 19, 57, 95, 285
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
718 : 1, 2, 359, 718
969 : 1, 3, 17, 19, 51, 57, 323, 969
802 : 1, 2, 401, 802
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,392,718,969,802, is 1.
Now, the common factors can be found like this.
285:3x 5x 19
392:2x 2x 2x 7x 7
718:2x 359
969:3x 17x 19
802:2x 401
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 3x 19 = 228
Therefore, the value for common factors is 228.
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 = 62338093584480/(1x228)
LCM = 62338093584480/228
LCM = 273412691160
Thus, we can understand that the LCM of 285,392,718,969,802 is 273412691160.
