Given numbers are 782,115,703,654,874
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,115,703,654,874 is 898834710.
Find LCM of 782,115,703,654,874 with Prime Factorization
| 2 | 782, 115, 703, 654, 874 |
| 19 | 391, 115, 703, 327, 437 |
| 23 | 391, 115, 37, 327, 23 |
| 17, 5, 37, 327, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 23 x 17 x 5 x 37 x 327 x 1 = 898834710
Therefore, the lowest common multiple of 782,115,703,654,874 is 898834710.
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 115 x 703 x 654 x 874 = 36136750680840
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
115 : 1, 5, 23, 115
703 : 1, 19, 37, 703
654 : 1, 2, 3, 6, 109, 218, 327, 654
874 : 1, 2, 19, 23, 38, 46, 437, 874
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,115,703,654,874, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
115:5x 23
703:19x 37
654:2x 3x 109
874:2x 19x 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 19x 23x 23 = 40204
Therefore, the value for common factors is 40204.
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 = 36136750680840/(1x40204)
LCM = 36136750680840/40204
LCM = 898834710
Thus, we can understand that the LCM of 782,115,703,654,874 is 898834710.
