Given numbers are 420,210,573,833,123
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,210,573,833,123 is 391393380.
Find LCM of 420,210,573,833,123 with Prime Factorization
| 2 | 420, 210, 573, 833, 123 |
| 3 | 210, 105, 573, 833, 123 |
| 5 | 70, 35, 191, 833, 41 |
| 7 | 14, 7, 191, 833, 41 |
| 2, 1, 191, 119, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 2 x 1 x 191 x 119 x 41 = 391393380
Therefore, the lowest common multiple of 420,210,573,833,123 is 391393380.
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.
420 x 210 x 573 x 833 x 123 = 5178134417400
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.
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
573 : 1, 3, 191, 573
833 : 1, 7, 17, 49, 119, 833
123 : 1, 3, 41, 123
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,210,573,833,123, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
210:2x 3x 5x 7
573:3x 191
833:7x 7x 17
123:3x 41
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 3x 3x 5x 7x 7 = 13230
Therefore, the value for common factors is 13230.
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 = 5178134417400/(1x13230)
LCM = 5178134417400/13230
LCM = 391393380
Thus, we can understand that the LCM of 420,210,573,833,123 is 391393380.
