Given numbers are 639,221,736,858,359
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,221,736,858,359 is 410447939616.
Find LCM of 639,221,736,858,359 with Prime Factorization
| 2 | 639, 221, 736, 858, 359 |
| 3 | 639, 221, 368, 429, 359 |
| 13 | 213, 221, 368, 143, 359 |
| 213, 17, 368, 11, 359 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 213 x 17 x 368 x 11 x 359 = 410447939616
Therefore, the lowest common multiple of 639,221,736,858,359 is 410447939616.
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 221 x 736 x 858 x 359 = 32014939290048
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
221 : 1, 13, 17, 221
736 : 1, 2, 4, 8, 16, 23, 32, 46, 92, 184, 368, 736
858 : 1, 2, 3, 6, 11, 13, 22, 26, 33, 39, 66, 78, 143, 286, 429, 858
359 : 1, 359
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,221,736,858,359, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
221:13x 17
736:2x 2x 2x 2x 2x 23
858:2x 3x 11x 13
359:359
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 13 = 78
Therefore, the value for common factors is 78.
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 = 32014939290048/(1x78)
LCM = 32014939290048/78
LCM = 410447939616
Thus, we can understand that the LCM of 639,221,736,858,359 is 410447939616.
