Given numbers are 287,678,584,618,730
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 287,678,584,618,730 is 29261842680.
Find LCM of 287,678,584,618,730 with Prime Factorization
| 2 | 287, 678, 584, 618, 730 |
| 3 | 287, 339, 292, 309, 365 |
| 73 | 287, 113, 292, 103, 365 |
| 287, 113, 4, 103, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 73 x 287 x 113 x 4 x 103 x 5 = 29261842680
Therefore, the lowest common multiple of 287,678,584,618,730 is 29261842680.
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.
287 x 678 x 584 x 618 x 730 = 51266748375360
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.
287 : 1, 7, 41, 287
678 : 1, 2, 3, 6, 113, 226, 339, 678
584 : 1, 2, 4, 8, 73, 146, 292, 584
618 : 1, 2, 3, 6, 103, 206, 309, 618
730 : 1, 2, 5, 10, 73, 146, 365, 730
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 287,678,584,618,730, is 1.
Now, the common factors can be found like this.
287:7x 41
678:2x 3x 113
584:2x 2x 2x 73
618:2x 3x 103
730:2x 5x 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 2x 3x 73 = 1752
Therefore, the value for common factors is 1752.
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 = 51266748375360/(1x1752)
LCM = 51266748375360/1752
LCM = 29261842680
Thus, we can understand that the LCM of 287,678,584,618,730 is 29261842680.
