Given numbers are 547,407,838,210
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 547,407,838,210 is 19589125710.
Find LCM of 547,407,838,210 with Prime Factorization
| 2 | 547, 407, 838, 210 |
| 547, 407, 419, 105 |
Multiply the prime numbers at the bottom and the left side.
2 x 547 x 407 x 419 x 105 = 19589125710
Therefore, the lowest common multiple of 547,407,838,210 is 19589125710.
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.
547 x 407 x 838 x 210 = 39178251420
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.
547 : 1, 547
407 : 1, 11, 37, 407
838 : 1, 2, 419, 838
210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 547,407,838,210, is 1.
Now, the common factors can be found like this.
547:547
407:11x 37
838:2x 419
210:2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
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 = 39178251420/(1x2)
LCM = 39178251420/2
LCM = 19589125710
Thus, we can understand that the LCM of 547,407,838,210 is 19589125710.
