Given numbers are 683,938,840,808
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 683,938,840,808 is 3882363240.
Find LCM of 683,938,840,808 with Prime Factorization
| 2 | 683, 938, 840, 808 |
| 2 | 683, 469, 420, 404 |
| 2 | 683, 469, 210, 202 |
| 7 | 683, 469, 105, 101 |
| 683, 67, 15, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 683 x 67 x 15 x 101 = 3882363240
Therefore, the lowest common multiple of 683,938,840,808 is 3882363240.
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.
683 x 938 x 840 x 808 = 434824682880
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.
683 : 1, 683
938 : 1, 2, 7, 14, 67, 134, 469, 938
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
808 : 1, 2, 4, 8, 101, 202, 404, 808
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 683,938,840,808, is 1.
Now, the common factors can be found like this.
683:683
938:2x 7x 67
840:2x 2x 2x 3x 5x 7
808:2x 2x 2x 101
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 7 = 112
Therefore, the value for common factors is 112.
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 = 434824682880/(1x112)
LCM = 434824682880/112
LCM = 3882363240
Thus, we can understand that the LCM of 683,938,840,808 is 3882363240.
