The LCM of 120,908,584,686,815 is 111176164680.
Find LCM of 120,908,584,686,815 with Prime Factorization
| 2 | 120, 908, 584, 686, 815 |
| 2 | 60, 454, 292, 343, 815 |
| 2 | 30, 227, 146, 343, 815 |
| 5 | 15, 227, 73, 343, 815 |
| 3, 227, 73, 343, 163 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 3 x 227 x 73 x 343 x 163 = 111176164680
Therefore, the lowest common multiple of 120,908,584,686,815 is 111176164680.
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.
120 x 908 x 584 x 686 x 815 = 35576372697600
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.
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
908 : 1, 2, 4, 227, 454, 908
584 : 1, 2, 4, 8, 73, 146, 292, 584
686 : 1, 2, 7, 14, 49, 98, 343, 686
815 : 1, 5, 163, 815
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,908,584,686,815, is 1.
Now, the common factors can be found like this.
120:2x 2x 2x 3x 5
908:2x 2x 227
584:2x 2x 2x 73
686:2x 7x 7x 7
815:5x 163
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 2x 2x 2x 2x 5 = 320
Therefore, the value for common factors is 320.
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 = 35576372697600/(1x320)
LCM = 35576372697600/320
LCM = 111176164680
Thus, we can understand that the LCM of 120,908,584,686,815 is 111176164680.
