Given numbers are 639,218,852,717
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,218,852,717 is 66586356.
Find LCM of 639,218,852,717 with Prime Factorization
| 2 | 639, 218, 852, 717 |
| 3 | 639, 109, 426, 717 |
| 71 | 213, 109, 142, 239 |
| 3, 109, 2, 239 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 71 x 3 x 109 x 2 x 239 = 66586356
Therefore, the lowest common multiple of 639,218,852,717 is 66586356.
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.
639 x 218 x 852 x 717 = 85097362968
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.
639 : 1, 3, 9, 71, 213, 639
218 : 1, 2, 109, 218
852 : 1, 2, 3, 4, 6, 12, 71, 142, 213, 284, 426, 852
717 : 1, 3, 239, 717
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,218,852,717, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
218:2x 109
852:2x 2x 3x 71
717:3x 239
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 71 = 1278
Therefore, the value for common factors is 1278.
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 = 85097362968/(1x1278)
LCM = 85097362968/1278
LCM = 66586356
Thus, we can understand that the LCM of 639,218,852,717 is 66586356.
