Given numbers are 428,574,778,611
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,574,778,611 is 29195537644.
Find LCM of 428,574,778,611 with Prime Factorization
| 2 | 428, 574, 778, 611 |
| 214, 287, 389, 611 |
Multiply the prime numbers at the bottom and the left side.
2 x 214 x 287 x 389 x 611 = 29195537644
Therefore, the lowest common multiple of 428,574,778,611 is 29195537644.
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.
428 x 574 x 778 x 611 = 116782150576
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.
428 : 1, 2, 4, 107, 214, 428
574 : 1, 2, 7, 14, 41, 82, 287, 574
778 : 1, 2, 389, 778
611 : 1, 13, 47, 611
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,574,778,611, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
574:2x 7x 41
778:2x 389
611:13x 47
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 116782150576/(1x4)
LCM = 116782150576/4
LCM = 29195537644
Thus, we can understand that the LCM of 428,574,778,611 is 29195537644.
