Find LCM of 639,855,377,690,208 with Prime Factorization
| 2 | 639, 855, 377, 690, 208 |
| 3 | 639, 855, 377, 345, 104 |
| 3 | 213, 285, 377, 115, 104 |
| 5 | 71, 95, 377, 115, 104 |
| 13 | 71, 19, 377, 23, 104 |
| 71, 19, 29, 23, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 13 x 71 x 19 x 29 x 23 x 8 = 8421968880
Therefore, the lowest common multiple of 639,855,377,690,208 is 8421968880.
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 855 x 377 x 690 x 208 = 29561110768800
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
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
377 : 1, 13, 29, 377
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
208 : 1, 2, 4, 8, 13, 16, 26, 52, 104, 208
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,855,377,690,208, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
855:3x 3x 5x 19
377:13x 29
690:2x 3x 5x 23
208:2x 2x 2x 2x 13
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 3x 5x 13 = 3510
Therefore, the value for common factors is 3510.
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 = 29561110768800/(1x3510)
LCM = 29561110768800/3510
LCM = 8421968880
Thus, we can understand that the LCM of 639,855,377,690,208 is 8421968880.
