Given numbers are 156,849,702,643,974
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 156,849,702,643,974 is 124420939812.
Find LCM of 156,849,702,643,974 with Prime Factorization
| 2 | 156, 849, 702, 643, 974 |
| 3 | 78, 849, 351, 643, 487 |
| 13 | 26, 283, 117, 643, 487 |
| 2, 283, 9, 643, 487 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 2 x 283 x 9 x 643 x 487 = 124420939812
Therefore, the lowest common multiple of 156,849,702,643,974 is 124420939812.
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.
156 x 849 x 702 x 643 x 974 = 58228999832016
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.
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
849 : 1, 3, 283, 849
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
643 : 1, 643
974 : 1, 2, 487, 974
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 156,849,702,643,974, is 1.
Now, the common factors can be found like this.
156:2x 2x 3x 13
849:3x 283
702:2x 3x 3x 3x 13
643:643
974:2x 487
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 13 = 468
Therefore, the value for common factors is 468.
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 = 58228999832016/(1x468)
LCM = 58228999832016/468
LCM = 124420939812
Thus, we can understand that the LCM of 156,849,702,643,974 is 124420939812.
