Given numbers are 556,607,678,840,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 556,607,678,840,779 is 6238765739640.
Find LCM of 556,607,678,840,779 with Prime Factorization
| 2 | 556, 607, 678, 840, 779 |
| 2 | 278, 607, 339, 420, 779 |
| 3 | 139, 607, 339, 210, 779 |
| 139, 607, 113, 70, 779 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 139 x 607 x 113 x 70 x 779 = 6238765739640
Therefore, the lowest common multiple of 556,607,678,840,779 is 6238765739640.
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.
556 x 607 x 678 x 840 x 779 = 149730377751360
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.
556 : 1, 2, 4, 139, 278, 556
607 : 1, 607
678 : 1, 2, 3, 6, 113, 226, 339, 678
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 556,607,678,840,779, is 1.
Now, the common factors can be found like this.
556:2x 2x 139
607:607
678:2x 3x 113
840:2x 2x 2x 3x 5x 7
779:19x 41
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 3 = 24
Therefore, the value for common factors is 24.
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 = 149730377751360/(1x24)
LCM = 149730377751360/24
LCM = 6238765739640
Thus, we can understand that the LCM of 556,607,678,840,779 is 6238765739640.
