Given numbers are 778,348,985,584,989
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,348,985,584,989 is 19253700999480.
Find LCM of 778,348,985,584,989 with Prime Factorization
| 2 | 778, 348, 985, 584, 989 |
| 2 | 389, 174, 985, 292, 989 |
| 389, 87, 985, 146, 989 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 389 x 87 x 985 x 146 x 989 = 19253700999480
Therefore, the lowest common multiple of 778,348,985,584,989 is 19253700999480.
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.
778 x 348 x 985 x 584 x 989 = 154029607995840
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.
778 : 1, 2, 389, 778
348 : 1, 2, 3, 4, 6, 12, 29, 58, 87, 116, 174, 348
985 : 1, 5, 197, 985
584 : 1, 2, 4, 8, 73, 146, 292, 584
989 : 1, 23, 43, 989
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,348,985,584,989, is 1.
Now, the common factors can be found like this.
778:2x 389
348:2x 2x 3x 29
985:5x 197
584:2x 2x 2x 73
989:23x 43
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 2 = 8
Therefore, the value for common factors is 8.
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 = 154029607995840/(1x8)
LCM = 154029607995840/8
LCM = 19253700999480
Thus, we can understand that the LCM of 778,348,985,584,989 is 19253700999480.
