Given numbers are 155,746,867,690,906
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 155,746,867,690,906 is 348172452330.
Find LCM of 155,746,867,690,906 with Prime Factorization
| 2 | 155, 746, 867, 690, 906 |
| 3 | 155, 373, 867, 345, 453 |
| 5 | 155, 373, 289, 115, 151 |
| 31, 373, 289, 23, 151 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 31 x 373 x 289 x 23 x 151 = 348172452330
Therefore, the lowest common multiple of 155,746,867,690,906 is 348172452330.
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.
155 x 746 x 867 x 690 x 906 = 62671041419400
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.
155 : 1, 5, 31, 155
746 : 1, 2, 373, 746
867 : 1, 3, 17, 51, 289, 867
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
906 : 1, 2, 3, 6, 151, 302, 453, 906
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 155,746,867,690,906, is 1.
Now, the common factors can be found like this.
155:5x 31
746:2x 373
867:3x 17x 17
690:2x 3x 5x 23
906:2x 3x 151
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 5 = 180
Therefore, the value for common factors is 180.
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 = 62671041419400/(1x180)
LCM = 62671041419400/180
LCM = 348172452330
Thus, we can understand that the LCM of 155,746,867,690,906 is 348172452330.
