Given numbers are 614,428,826,520
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 614,428,826,520 is 7054651240.
Find LCM of 614,428,826,520 with Prime Factorization
| 2 | 614, 428, 826, 520 |
| 2 | 307, 214, 413, 260 |
| 307, 107, 413, 130 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 307 x 107 x 413 x 130 = 7054651240
Therefore, the lowest common multiple of 614,428,826,520 is 7054651240.
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.
614 x 428 x 826 x 520 = 112874419840
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.
614 : 1, 2, 307, 614
428 : 1, 2, 4, 107, 214, 428
826 : 1, 2, 7, 14, 59, 118, 413, 826
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 614,428,826,520, is 2.
Now, the common factors can be found like this.
614:2x 307
428:2x 2x 107
826:2x 7x 59
520:2x 2x 2x 5x 13
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 2 = 8
Therefore, the value for common factors is 8.
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 = 112874419840/(2x8)
LCM = 112874419840/16
LCM = 7054651240
Thus, we can understand that the LCM of 614,428,826,520 is 7054651240.
