Given numbers are 581,820,634,994,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 581,820,634,994,247 is 2648527880180.
Find LCM of 581,820,634,994,247 with Prime Factorization
| 2 | 581, 820, 634, 994, 247 |
| 7 | 581, 410, 317, 497, 247 |
| 83, 410, 317, 71, 247 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 83 x 410 x 317 x 71 x 247 = 2648527880180
Therefore, the lowest common multiple of 581,820,634,994,247 is 2648527880180.
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.
581 x 820 x 634 x 994 x 247 = 74158780645040
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.
581 : 1, 7, 83, 581
820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820
634 : 1, 2, 317, 634
994 : 1, 2, 7, 14, 71, 142, 497, 994
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 581,820,634,994,247, is 1.
Now, the common factors can be found like this.
581:7x 83
820:2x 2x 5x 41
634:2x 317
994:2x 7x 71
247:13x 19
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 7 = 28
Therefore, the value for common factors is 28.
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 = 74158780645040/(1x28)
LCM = 74158780645040/28
LCM = 2648527880180
Thus, we can understand that the LCM of 581,820,634,994,247 is 2648527880180.
