Given numbers are 855,727,312,507
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,727,312,507 is 840382920.
Find LCM of 855,727,312,507 with Prime Factorization
| 3 | 855, 727, 312, 507 |
| 13 | 285, 727, 104, 169 |
| 285, 727, 8, 13 |
Multiply the prime numbers at the bottom and the left side.
3 x 13 x 285 x 727 x 8 x 13 = 840382920
Therefore, the lowest common multiple of 855,727,312,507 is 840382920.
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.
855 x 727 x 312 x 507 = 98324801640
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.
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
727 : 1, 727
312 : 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, 312
507 : 1, 3, 13, 39, 169, 507
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,727,312,507, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
727:727
312:2x 2x 2x 3x 13
507:3x 13x 13
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 13 = 117
Therefore, the value for common factors is 117.
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 = 98324801640/(1x117)
LCM = 98324801640/117
LCM = 840382920
Thus, we can understand that the LCM of 855,727,312,507 is 840382920.
