Given numbers are 730,230,621,687,631
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 730,230,621,687,631 is 65505731670.
Find LCM of 730,230,621,687,631 with Prime Factorization
| 2 | 730, 230, 621, 687, 631 |
| 3 | 365, 115, 621, 687, 631 |
| 5 | 365, 115, 207, 229, 631 |
| 23 | 73, 23, 207, 229, 631 |
| 73, 1, 9, 229, 631 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 73 x 1 x 9 x 229 x 631 = 65505731670
Therefore, the lowest common multiple of 730,230,621,687,631 is 65505731670.
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 230 x 621 x 687 x 631 = 45198954852300
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
230 : 1, 2, 5, 10, 23, 46, 115, 230
621 : 1, 3, 9, 23, 27, 69, 207, 621
687 : 1, 3, 229, 687
631 : 1, 631
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 730,230,621,687,631, is 1.
Now, the common factors can be found like this.
730:2x 5x 73
230:2x 5x 23
621:3x 3x 3x 23
687:3x 229
631:631
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5x 23 = 690
Therefore, the value for common factors is 690.
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 = 45198954852300/(1x690)
LCM = 45198954852300/690
LCM = 65505731670
Thus, we can understand that the LCM of 730,230,621,687,631 is 65505731670.
