Given numbers are 699,855,542,813
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 699,855,542,813 is 107974530.
Find LCM of 699,855,542,813 with Prime Factorization
| 3 | 699, 855, 542, 813 |
| 271 | 233, 285, 542, 271 |
| 233, 285, 2, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 271 x 233 x 285 x 2 x 1 = 107974530
Therefore, the lowest common multiple of 699,855,542,813 is 107974530.
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.
699 x 855 x 542 x 813 = 263349878670
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.
699 : 1, 3, 233, 699
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
542 : 1, 2, 271, 542
813 : 1, 3, 271, 813
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,855,542,813, is 1.
Now, the common factors can be found like this.
699:3x 233
855:3x 3x 5x 19
542:2x 271
813:3x 271
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 271 = 2439
Therefore, the value for common factors is 2439.
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 = 263349878670/(1x2439)
LCM = 263349878670/2439
LCM = 107974530
Thus, we can understand that the LCM of 699,855,542,813 is 107974530.
