Given numbers are 903,665,363,287
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 903,665,363,287 is 425579385.
Find LCM of 903,665,363,287 with Prime Factorization
| 3 | 903, 665, 363, 287 |
| 7 | 301, 665, 121, 287 |
| 43, 95, 121, 41 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 43 x 95 x 121 x 41 = 425579385
Therefore, the lowest common multiple of 903,665,363,287 is 425579385.
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.
903 x 665 x 363 x 287 = 62560169595
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.
903 : 1, 3, 7, 21, 43, 129, 301, 903
665 : 1, 5, 7, 19, 35, 95, 133, 665
363 : 1, 3, 11, 33, 121, 363
287 : 1, 7, 41, 287
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 903,665,363,287, is 1.
Now, the common factors can be found like this.
903:3x 7x 43
665:5x 7x 19
363:3x 11x 11
287:7x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 7x 7 = 147
Therefore, the value for common factors is 147.
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 = 62560169595/(1x147)
LCM = 62560169595/147
LCM = 425579385
Thus, we can understand that the LCM of 903,665,363,287 is 425579385.
