Given numbers are 574,242,287,870
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 574,242,287,870 is 30212490.
Find LCM of 574,242,287,870 with Prime Factorization
| 2 | 574, 242, 287, 870 |
| 7 | 287, 121, 287, 435 |
| 41 | 41, 121, 41, 435 |
| 1, 121, 1, 435 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 41 x 1 x 121 x 1 x 435 = 30212490
Therefore, the lowest common multiple of 574,242,287,870 is 30212490.
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.
574 x 242 x 287 x 870 = 34683938520
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.
574 : 1, 2, 7, 14, 41, 82, 287, 574
242 : 1, 2, 11, 22, 121, 242
287 : 1, 7, 41, 287
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 574,242,287,870, is 1.
Now, the common factors can be found like this.
574:2x 7x 41
242:2x 11x 11
287:7x 41
870:2x 3x 5x 29
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 7x 41 = 1148
Therefore, the value for common factors is 1148.
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 = 34683938520/(1x1148)
LCM = 34683938520/1148
LCM = 30212490
Thus, we can understand that the LCM of 574,242,287,870 is 30212490.
