Given numbers are 663,913,542,392,455
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 663,913,542,392,455 is 321521240040.
Find LCM of 663,913,542,392,455 with Prime Factorization
| 2 | 663, 913, 542, 392, 455 |
| 7 | 663, 913, 271, 196, 455 |
| 13 | 663, 913, 271, 28, 65 |
| 51, 913, 271, 28, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 13 x 51 x 913 x 271 x 28 x 5 = 321521240040
Therefore, the lowest common multiple of 663,913,542,392,455 is 321521240040.
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.
663 x 913 x 542 x 392 x 455 = 58516865687280
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.
663 : 1, 3, 13, 17, 39, 51, 221, 663
913 : 1, 11, 83, 913
542 : 1, 2, 271, 542
392 : 1, 2, 4, 7, 8, 14, 28, 49, 56, 98, 196, 392
455 : 1, 5, 7, 13, 35, 65, 91, 455
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,913,542,392,455, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
913:11x 83
542:2x 271
392:2x 2x 2x 7x 7
455:5x 7x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 13 = 182
Therefore, the value for common factors is 182.
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 = 58516865687280/(1x182)
LCM = 58516865687280/182
LCM = 321521240040
Thus, we can understand that the LCM of 663,913,542,392,455 is 321521240040.
