Given numbers are 730,205,133,742,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 730,205,133,742,438 is 632929710.
Find LCM of 730,205,133,742,438 with Prime Factorization
| 2 | 730, 205, 133, 742, 438 |
| 5 | 365, 205, 133, 371, 219 |
| 7 | 73, 41, 133, 371, 219 |
| 73 | 73, 41, 19, 53, 219 |
| 1, 41, 19, 53, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 73 x 1 x 41 x 19 x 53 x 3 = 632929710
Therefore, the lowest common multiple of 730,205,133,742,438 is 632929710.
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.
730 x 205 x 133 x 742 x 438 = 6468541636200
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.
730 : 1, 2, 5, 10, 73, 146, 365, 730
205 : 1, 5, 41, 205
133 : 1, 7, 19, 133
742 : 1, 2, 7, 14, 53, 106, 371, 742
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,205,133,742,438, is 1.
Now, the common factors can be found like this.
730:2x 5x 73
205:5x 41
133:7x 19
742:2x 7x 53
438:2x 3x 73
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 5x 7x 73 = 10220
Therefore, the value for common factors is 10220.
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 = 6468541636200/(1x10220)
LCM = 6468541636200/10220
LCM = 632929710
Thus, we can understand that the LCM of 730,205,133,742,438 is 632929710.
