Given numbers are 446,568,638,580
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 446,568,638,580 is 202029080.
Find LCM of 446,568,638,580 with Prime Factorization
| 2 | 446, 568, 638, 580 |
| 2 | 223, 284, 319, 290 |
| 29 | 223, 142, 319, 145 |
| 223, 142, 11, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 29 x 223 x 142 x 11 x 5 = 202029080
Therefore, the lowest common multiple of 446,568,638,580 is 202029080.
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.
446 x 568 x 638 x 580 = 93741493120
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.
446 : 1, 2, 223, 446
568 : 1, 2, 4, 8, 71, 142, 284, 568
638 : 1, 2, 11, 22, 29, 58, 319, 638
580 : 1, 2, 4, 5, 10, 20, 29, 58, 116, 145, 290, 580
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 446,568,638,580, is 2.
Now, the common factors can be found like this.
446:2x 223
568:2x 2x 2x 71
638:2x 11x 29
580:2x 2x 5x 29
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 2x 29 = 232
Therefore, the value for common factors is 232.
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 = 93741493120/(2x232)
LCM = 93741493120/464
LCM = 202029080
Thus, we can understand that the LCM of 446,568,638,580 is 202029080.
