The LCM of 652,684,789,639 is 2081890116.
Find LCM of 652,684,789,639 with Prime Factorization
| 2 | 652, 684, 789, 639 |
| 2 | 326, 342, 789, 639 |
| 3 | 163, 171, 789, 639 |
| 3 | 163, 57, 263, 213 |
| 163, 19, 263, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 163 x 19 x 263 x 71 = 2081890116
Therefore, the lowest common multiple of 652,684,789,639 is 2081890116.
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.
652 x 684 x 789 x 639 = 224844132528
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.
652 : 1, 2, 4, 163, 326, 652
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
789 : 1, 3, 263, 789
639 : 1, 3, 9, 71, 213, 639
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 652,684,789,639, is 1.
Now, the common factors can be found like this.
652:2x 2x 163
684:2x 2x 3x 3x 19
789:3x 263
639:3x 3x 71
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 3x 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 224844132528/(1x108)
LCM = 224844132528/108
LCM = 2081890116
Thus, we can understand that the LCM of 652,684,789,639 is 2081890116.
