Given numbers are 682,924,694,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 682,924,694,420 is 49697340.
Find LCM of 682,924,694,420 with Prime Factorization
| 2 | 682, 924, 694, 420 |
| 2 | 341, 462, 347, 210 |
| 3 | 341, 231, 347, 105 |
| 7 | 341, 77, 347, 35 |
| 11 | 341, 11, 347, 5 |
| 31, 1, 347, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 7 x 11 x 31 x 1 x 347 x 5 = 49697340
Therefore, the lowest common multiple of 682,924,694,420 is 49697340.
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.
682 x 924 x 694 x 420 = 183681368640
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.
682 : 1, 2, 11, 22, 31, 62, 341, 682
924 : 1, 2, 3, 4, 6, 7, 11, 12, 14, 21, 22, 28, 33, 42, 44, 66, 77, 84, 132, 154, 231, 308, 462, 924
694 : 1, 2, 347, 694
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 682,924,694,420, is 2.
Now, the common factors can be found like this.
682:2x 11x 31
924:2x 2x 3x 7x 11
694:2x 347
420:2x 2x 3x 5x 7
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 2x 3x 7x 11 = 1848
Therefore, the value for common factors is 1848.
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 = 183681368640/(2x1848)
LCM = 183681368640/3696
LCM = 49697340
Thus, we can understand that the LCM of 682,924,694,420 is 49697340.
