Given numbers are 578,620,836,814
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 578,620,836,814 is 1385598940.
Find LCM of 578,620,836,814 with Prime Factorization
| 2 | 578, 620, 836, 814 |
| 2 | 289, 310, 418, 407 |
| 11 | 289, 155, 209, 407 |
| 289, 155, 19, 37 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 11 x 289 x 155 x 19 x 37 = 1385598940
Therefore, the lowest common multiple of 578,620,836,814 is 1385598940.
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 620 x 836 x 814 = 243865413440
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
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
814 : 1, 2, 11, 22, 37, 74, 407, 814
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 578,620,836,814, is 2.
Now, the common factors can be found like this.
578:2x 17x 17
620:2x 2x 5x 31
836:2x 2x 11x 19
814:2x 11x 37
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 11 = 88
Therefore, the value for common factors is 88.
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 = 243865413440/(2x88)
LCM = 243865413440/176
LCM = 1385598940
Thus, we can understand that the LCM of 578,620,836,814 is 1385598940.
