Given numbers are 219,308,729,103,820
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 219,308,729,103,820 is 346092502140.
Find LCM of 219,308,729,103,820 with Prime Factorization
| 2 | 219, 308, 729, 103, 820 |
| 2 | 219, 154, 729, 103, 410 |
| 3 | 219, 77, 729, 103, 205 |
| 73, 77, 243, 103, 205 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 73 x 77 x 243 x 103 x 205 = 346092502140
Therefore, the lowest common multiple of 219,308,729,103,820 is 346092502140.
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.
219 x 308 x 729 x 103 x 820 = 4153110025680
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.
219 : 1, 3, 73, 219
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
729 : 1, 3, 9, 27, 81, 243, 729
103 : 1, 103
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 219,308,729,103,820, is 1.
Now, the common factors can be found like this.
219:3x 73
308:2x 2x 7x 11
729:3x 3x 3x 3x 3x 3
103:103
820:2x 2x 5x 41
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 3 = 12
Therefore, the value for common factors is 12.
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 = 4153110025680/(1x12)
LCM = 4153110025680/12
LCM = 346092502140
Thus, we can understand that the LCM of 219,308,729,103,820 is 346092502140.
