Given numbers are 607,489,663,641
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 607,489,663,641 is 42048243003.
Find LCM of 607,489,663,641 with Prime Factorization
| 3 | 607, 489, 663, 641 |
| 607, 163, 221, 641 |
Multiply the prime numbers at the bottom and the left side.
3 x 607 x 163 x 221 x 641 = 42048243003
Therefore, the lowest common multiple of 607,489,663,641 is 42048243003.
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.
607 x 489 x 663 x 641 = 126144729009
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.
607 : 1, 607
489 : 1, 3, 163, 489
663 : 1, 3, 13, 17, 39, 51, 221, 663
641 : 1, 641
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 607,489,663,641, is 1.
Now, the common factors can be found like this.
607:607
489:3x 163
663:3x 13x 17
641:641
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3 = 3
Therefore, the value for common factors is 3.
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 = 126144729009/(1x3)
LCM = 126144729009/3
LCM = 42048243003
Thus, we can understand that the LCM of 607,489,663,641 is 42048243003.
