Given numbers are 521,605,655,528,218
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 521,605,655,528,218 is 216038985360.
Find LCM of 521,605,655,528,218 with Prime Factorization
| 2 | 521, 605, 655, 528, 218 |
| 5 | 521, 605, 655, 264, 109 |
| 11 | 521, 121, 131, 264, 109 |
| 521, 11, 131, 24, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 11 x 521 x 11 x 131 x 24 x 109 = 216038985360
Therefore, the lowest common multiple of 521,605,655,528,218 is 216038985360.
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.
521 x 605 x 655 x 528 x 218 = 23764288389600
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.
521 : 1, 521
605 : 1, 5, 11, 55, 121, 605
655 : 1, 5, 131, 655
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
218 : 1, 2, 109, 218
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 521,605,655,528,218, is 1.
Now, the common factors can be found like this.
521:521
605:5x 11x 11
655:5x 131
528:2x 2x 2x 2x 3x 11
218:2x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 11 = 110
Therefore, the value for common factors is 110.
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 = 23764288389600/(1x110)
LCM = 23764288389600/110
LCM = 216038985360
Thus, we can understand that the LCM of 521,605,655,528,218 is 216038985360.
