Given numbers are 628,811,553,237,860
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 628,811,553,237,860 is 181662523980.
Find LCM of 628,811,553,237,860 with Prime Factorization
| 2 | 628, 811, 553, 237, 860 |
| 2 | 314, 811, 553, 237, 430 |
| 79 | 157, 811, 553, 237, 215 |
| 157, 811, 7, 3, 215 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 79 x 157 x 811 x 7 x 3 x 215 = 181662523980
Therefore, the lowest common multiple of 628,811,553,237,860 is 181662523980.
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.
628 x 811 x 553 x 237 x 860 = 57405357577680
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.
628 : 1, 2, 4, 157, 314, 628
811 : 1, 811
553 : 1, 7, 79, 553
237 : 1, 3, 79, 237
860 : 1, 2, 4, 5, 10, 20, 43, 86, 172, 215, 430, 860
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 628,811,553,237,860, is 1.
Now, the common factors can be found like this.
628:2x 2x 157
811:811
553:7x 79
237:3x 79
860:2x 2x 5x 43
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 79 = 316
Therefore, the value for common factors is 316.
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 = 57405357577680/(1x316)
LCM = 57405357577680/316
LCM = 181662523980
Thus, we can understand that the LCM of 628,811,553,237,860 is 181662523980.
