Given numbers are 782,639,387,730,506
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,639,387,730,506 is 86270361210.
Find LCM of 782,639,387,730,506 with Prime Factorization
| 2 | 782, 639, 387, 730, 506 |
| 3 | 391, 639, 387, 365, 253 |
| 3 | 391, 213, 129, 365, 253 |
| 23 | 391, 71, 43, 365, 253 |
| 17, 71, 43, 365, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 23 x 17 x 71 x 43 x 365 x 11 = 86270361210
Therefore, the lowest common multiple of 782,639,387,730,506 is 86270361210.
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.
782 x 639 x 387 x 730 x 506 = 71431859081880
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
639 : 1, 3, 9, 71, 213, 639
387 : 1, 3, 9, 43, 129, 387
730 : 1, 2, 5, 10, 73, 146, 365, 730
506 : 1, 2, 11, 22, 23, 46, 253, 506
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,639,387,730,506, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
639:3x 3x 71
387:3x 3x 43
730:2x 5x 73
506:2x 11x 23
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 23 = 828
Therefore, the value for common factors is 828.
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 = 71431859081880/(1x828)
LCM = 71431859081880/828
LCM = 86270361210
Thus, we can understand that the LCM of 782,639,387,730,506 is 86270361210.
