Given numbers are 428,878,114,779,493
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,878,114,779,493 is 216478076772.
Find LCM of 428,878,114,779,493 with Prime Factorization
| 2 | 428, 878, 114, 779, 493 |
| 19 | 214, 439, 57, 779, 493 |
| 214, 439, 3, 41, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 19 x 214 x 439 x 3 x 41 x 493 = 216478076772
Therefore, the lowest common multiple of 428,878,114,779,493 is 216478076772.
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 878 x 114 x 779 x 493 = 16452333834672
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
878 : 1, 2, 439, 878
114 : 1, 2, 3, 6, 19, 38, 57, 114
779 : 1, 19, 41, 779
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,878,114,779,493, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
878:2x 439
114:2x 3x 19
779:19x 41
493:17x 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 19 = 76
Therefore, the value for common factors is 76.
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 = 16452333834672/(1x76)
LCM = 16452333834672/76
LCM = 216478076772
Thus, we can understand that the LCM of 428,878,114,779,493 is 216478076772.
