Given numbers are 705,893,639,779
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,893,639,779 is 116978535.
Find LCM of 705,893,639,779 with Prime Factorization
| 3 | 705, 893, 639, 779 |
| 19 | 235, 893, 213, 779 |
| 47 | 235, 47, 213, 41 |
| 5, 1, 213, 41 |
Multiply the prime numbers at the bottom and the left side.
3 x 19 x 47 x 5 x 1 x 213 x 41 = 116978535
Therefore, the lowest common multiple of 705,893,639,779 is 116978535.
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.
705 x 893 x 639 x 779 = 313385495265
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
893 : 1, 19, 47, 893
639 : 1, 3, 9, 71, 213, 639
779 : 1, 19, 41, 779
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,893,639,779, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
893:19x 47
639:3x 3x 71
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.
3x 19x 47 = 2679
Therefore, the value for common factors is 2679.
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 = 313385495265/(1x2679)
LCM = 313385495265/2679
LCM = 116978535
Thus, we can understand that the LCM of 705,893,639,779 is 116978535.
