The LCM of 630,428,581,249,517 is 5785261020.
Find LCM of 630,428,581,249,517 with Prime Factorization
| 2 | 630, 428, 581, 249, 517 |
| 3 | 315, 214, 581, 249, 517 |
| 7 | 105, 214, 581, 83, 517 |
| 83 | 15, 214, 83, 83, 517 |
| 15, 214, 1, 1, 517 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 83 x 15 x 214 x 1 x 1 x 517 = 5785261020
Therefore, the lowest common multiple of 630,428,581,249,517 is 5785261020.
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.
630 x 428 x 581 x 249 x 517 = 20167419915720
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.
630 : 1, 2, 3, 5, 6, 7, 9, 10, 14, 15, 18, 21, 30, 35, 42, 45, 63, 70, 90, 105, 126, 210, 315, 630
428 : 1, 2, 4, 107, 214, 428
581 : 1, 7, 83, 581
249 : 1, 3, 83, 249
517 : 1, 11, 47, 517
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 630,428,581,249,517, is 1.
Now, the common factors can be found like this.
630:2x 3x 3x 5x 7
428:2x 2x 107
581:7x 83
249:3x 83
517:11x 47
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 7x 83 = 3486
Therefore, the value for common factors is 3486.
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 = 20167419915720/(1x3486)
LCM = 20167419915720/3486
LCM = 5785261020
Thus, we can understand that the LCM of 630,428,581,249,517 is 5785261020.
