The LCM of 684,639,504,497 is 679896.
Find LCM of 684,639,504,497 with Prime Factorization
| 2 | 684, 639, 504, 497 |
| 2 | 342, 639, 252, 497 |
| 3 | 171, 639, 126, 497 |
| 3 | 57, 213, 42, 497 |
| 7 | 19, 71, 14, 497 |
| 71 | 19, 71, 2, 71 |
| 19, 1, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 3 x 7 x 71 x 19 x 1 x 2 x 1 = 679896
Therefore, the lowest common multiple of 684,639,504,497 is 679896.
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.
684 x 639 x 504 x 497 = 109482293088
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.
684 : 1, 2, 3, 4, 6, 9, 12, 18, 19, 36, 38, 57, 76, 114, 171, 228, 342, 684
639 : 1, 3, 9, 71, 213, 639
504 : 1, 2, 3, 4, 6, 7, 8, 9, 12, 14, 18, 21, 24, 28, 36, 42, 56, 63, 72, 84, 126, 168, 252, 504
497 : 1, 7, 71, 497
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 684,639,504,497, is 1.
Now, the common factors can be found like this.
684:2x 2x 3x 3x 19
639:3x 3x 71
504:2x 2x 2x 3x 3x 7
497:7x 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 3x 3x 7x 71 = 161028
Therefore, the value for common factors is 161028.
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 = 109482293088/(1x161028)
LCM = 109482293088/161028
LCM = 679896
Thus, we can understand that the LCM of 684,639,504,497 is 679896.
