The LCM of 639,338,676,209,131 is 11826742356.
Find LCM of 639,338,676,209,131 with Prime Factorization
| 2 | 639, 338, 676, 209, 131 |
| 13 | 639, 169, 338, 209, 131 |
| 13 | 639, 13, 26, 209, 131 |
| 639, 1, 2, 209, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 13 x 639 x 1 x 2 x 209 x 131 = 11826742356
Therefore, the lowest common multiple of 639,338,676,209,131 is 11826742356.
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 338 x 676 x 209 x 131 = 3997438916328
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
338 : 1, 2, 13, 26, 169, 338
676 : 1, 2, 4, 13, 26, 52, 169, 338, 676
209 : 1, 11, 19, 209
131 : 1, 131
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,338,676,209,131, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
338:2x 13x 13
676:2x 2x 13x 13
209:11x 19
131:131
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 13x 13 = 338
Therefore, the value for common factors is 338.
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 = 3997438916328/(1x338)
LCM = 3997438916328/338
LCM = 11826742356
Thus, we can understand that the LCM of 639,338,676,209,131 is 11826742356.
