Given numbers are 721,146,180,309,908
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 721,146,180,309,908 is 2150584380.
Find LCM of 721,146,180,309,908 with Prime Factorization
| 2 | 721, 146, 180, 309, 908 |
| 2 | 721, 73, 90, 309, 454 |
| 3 | 721, 73, 45, 309, 227 |
| 103 | 721, 73, 15, 103, 227 |
| 7, 73, 15, 1, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 103 x 7 x 73 x 15 x 1 x 227 = 2150584380
Therefore, the lowest common multiple of 721,146,180,309,908 is 2150584380.
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.
721 x 146 x 180 x 309 x 908 = 5316244587360
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.
721 : 1, 7, 103, 721
146 : 1, 2, 73, 146
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
309 : 1, 3, 103, 309
908 : 1, 2, 4, 227, 454, 908
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 721,146,180,309,908, is 1.
Now, the common factors can be found like this.
721:7x 103
146:2x 73
180:2x 2x 3x 3x 5
309:3x 103
908:2x 2x 227
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 2x 3x 103 = 2472
Therefore, the value for common factors is 2472.
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 = 5316244587360/(1x2472)
LCM = 5316244587360/2472
LCM = 2150584380
Thus, we can understand that the LCM of 721,146,180,309,908 is 2150584380.
