Given numbers are 578,440,655,857
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,440,655,857 is 14275871720.
Find LCM of 578,440,655,857 with Prime Factorization
| 2 | 578, 440, 655, 857 |
| 5 | 289, 220, 655, 857 |
| 289, 44, 131, 857 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 289 x 44 x 131 x 857 = 14275871720
Therefore, the lowest common multiple of 578,440,655,857 is 14275871720.
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.
578 x 440 x 655 x 857 = 142758717200
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.
578 : 1, 2, 17, 34, 289, 578
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
655 : 1, 5, 131, 655
857 : 1, 857
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,440,655,857, is 1.
Now, the common factors can be found like this.
578:2x 17x 17
440:2x 2x 2x 5x 11
655:5x 131
857:857
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 142758717200/(1x10)
LCM = 142758717200/10
LCM = 14275871720
Thus, we can understand that the LCM of 578,440,655,857 is 14275871720.
