Given numbers are 285,318,638,754
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 285,318,638,754 is 125280870.
Find LCM of 285,318,638,754 with Prime Factorization
| 2 | 285, 318, 638, 754 |
| 3 | 285, 159, 319, 377 |
| 29 | 95, 53, 319, 377 |
| 95, 53, 11, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 29 x 95 x 53 x 11 x 13 = 125280870
Therefore, the lowest common multiple of 285,318,638,754 is 125280870.
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 318 x 638 x 754 = 43597742760
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
318 : 1, 2, 3, 6, 53, 106, 159, 318
638 : 1, 2, 11, 22, 29, 58, 319, 638
754 : 1, 2, 13, 26, 29, 58, 377, 754
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 285,318,638,754, is 1.
Now, the common factors can be found like this.
285:3x 5x 19
318:2x 3x 53
638:2x 11x 29
754:2x 13x 29
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 29 = 348
Therefore, the value for common factors is 348.
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 = 43597742760/(1x348)
LCM = 43597742760/348
LCM = 125280870
Thus, we can understand that the LCM of 285,318,638,754 is 125280870.
