Given numbers are 668,821,990,377
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 668,821,990,377 is 102344891220.
Find LCM of 668,821,990,377 with Prime Factorization
| 2 | 668, 821, 990, 377 |
| 334, 821, 495, 377 |
Multiply the prime numbers at the bottom and the left side.
2 x 334 x 821 x 495 x 377 = 102344891220
Therefore, the lowest common multiple of 668,821,990,377 is 102344891220.
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.
668 x 821 x 990 x 377 = 204689782440
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.
668 : 1, 2, 4, 167, 334, 668
821 : 1, 821
990 : 1, 2, 3, 5, 6, 9, 10, 11, 15, 18, 22, 30, 33, 45, 55, 66, 90, 99, 110, 165, 198, 330, 495, 990
377 : 1, 13, 29, 377
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 668,821,990,377, is 1.
Now, the common factors can be found like this.
668:2x 2x 167
821:821
990:2x 3x 3x 5x 11
377:13x 29
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 = 204689782440/(1x2)
LCM = 204689782440/2
LCM = 102344891220
Thus, we can understand that the LCM of 668,821,990,377 is 102344891220.
