Given numbers are 327,428,720,570,638
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 327,428,720,570,638 is 50896398960.
Find LCM of 327,428,720,570,638 with Prime Factorization
| 2 | 327, 428, 720, 570, 638 |
| 2 | 327, 214, 360, 285, 319 |
| 3 | 327, 107, 180, 285, 319 |
| 5 | 109, 107, 60, 95, 319 |
| 109, 107, 12, 19, 319 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 109 x 107 x 12 x 19 x 319 = 50896398960
Therefore, the lowest common multiple of 327,428,720,570,638 is 50896398960.
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.
327 x 428 x 720 x 570 x 638 = 36645407251200
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.
327 : 1, 3, 109, 327
428 : 1, 2, 4, 107, 214, 428
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
570 : 1, 2, 3, 5, 6, 10, 15, 19, 30, 38, 57, 95, 114, 190, 285, 570
638 : 1, 2, 11, 22, 29, 58, 319, 638
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 327,428,720,570,638, is 1.
Now, the common factors can be found like this.
327:3x 109
428:2x 2x 107
720:2x 2x 2x 2x 3x 3x 5
570:2x 3x 5x 19
638:2x 11x 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 2x 2x 3x 3x 5 = 720
Therefore, the value for common factors is 720.
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 = 36645407251200/(1x720)
LCM = 36645407251200/720
LCM = 50896398960
Thus, we can understand that the LCM of 327,428,720,570,638 is 50896398960.
