Given numbers are 481,682,620,478
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 481,682,620,478 is 784020380.
Find LCM of 481,682,620,478 with Prime Factorization
| 2 | 481, 682, 620, 478 |
| 31 | 481, 341, 310, 239 |
| 481, 11, 10, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 31 x 481 x 11 x 10 x 239 = 784020380
Therefore, the lowest common multiple of 481,682,620,478 is 784020380.
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.
481 x 682 x 620 x 478 = 97218527120
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.
481 : 1, 13, 37, 481
682 : 1, 2, 11, 22, 31, 62, 341, 682
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
478 : 1, 2, 239, 478
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 481,682,620,478, is 1.
Now, the common factors can be found like this.
481:13x 37
682:2x 11x 31
620:2x 2x 5x 31
478:2x 239
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 31 = 124
Therefore, the value for common factors is 124.
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 = 97218527120/(1x124)
LCM = 97218527120/124
LCM = 784020380
Thus, we can understand that the LCM of 481,682,620,478 is 784020380.
