Given numbers are 120,834,783,506,355
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 120,834,783,506,355 is 78201561240.
Find LCM of 120,834,783,506,355 with Prime Factorization
| 2 | 120, 834, 783, 506, 355 |
| 3 | 60, 417, 783, 253, 355 |
| 5 | 20, 139, 261, 253, 355 |
| 4, 139, 261, 253, 71 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 4 x 139 x 261 x 253 x 71 = 78201561240
Therefore, the lowest common multiple of 120,834,783,506,355 is 78201561240.
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 834 x 783 x 506 x 355 = 14076281023200
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
834 : 1, 2, 3, 6, 139, 278, 417, 834
783 : 1, 3, 9, 27, 29, 87, 261, 783
506 : 1, 2, 11, 22, 23, 46, 253, 506
355 : 1, 5, 71, 355
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 120,834,783,506,355, is 1.
Now, the common factors can be found like this.
120:2x 2x 2x 3x 5
834:2x 3x 139
783:3x 3x 3x 29
506:2x 11x 23
355:5x 71
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 = 14076281023200/(1x180)
LCM = 14076281023200/180
LCM = 78201561240
Thus, we can understand that the LCM of 120,834,783,506,355 is 78201561240.
