Given numbers are 646,627,723,658,155
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 646,627,723,658,155 is 261993849810.
Find LCM of 646,627,723,658,155 with Prime Factorization
| 2 | 646, 627, 723, 658, 155 |
| 3 | 323, 627, 723, 329, 155 |
| 19 | 323, 209, 241, 329, 155 |
| 17, 11, 241, 329, 155 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 19 x 17 x 11 x 241 x 329 x 155 = 261993849810
Therefore, the lowest common multiple of 646,627,723,658,155 is 261993849810.
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.
646 x 627 x 723 x 658 x 155 = 29867298878340
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.
646 : 1, 2, 17, 19, 34, 38, 323, 646
627 : 1, 3, 11, 19, 33, 57, 209, 627
723 : 1, 3, 241, 723
658 : 1, 2, 7, 14, 47, 94, 329, 658
155 : 1, 5, 31, 155
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 646,627,723,658,155, is 1.
Now, the common factors can be found like this.
646:2x 17x 19
627:3x 11x 19
723:3x 241
658:2x 7x 47
155:5x 31
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 19 = 114
Therefore, the value for common factors is 114.
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 = 29867298878340/(1x114)
LCM = 29867298878340/114
LCM = 261993849810
Thus, we can understand that the LCM of 646,627,723,658,155 is 261993849810.
