Given numbers are 855,689,152,643
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 855,689,152,643 is 3030304680.
Find LCM of 855,689,152,643 with Prime Factorization
19 | 855, 689, 152, 643 |
45, 689, 8, 643 |
Multiply the prime numbers at the bottom and the left side.
19 x 45 x 689 x 8 x 643 = 3030304680
Therefore, the lowest common multiple of 855,689,152,643 is 3030304680.
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 689 x 152 x 643 = 57575788920
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
689 : 1, 13, 53, 689
152 : 1, 2, 4, 8, 19, 38, 76, 152
643 : 1, 643
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 855,689,152,643, is 1.
Now, the common factors can be found like this.
855:3x 3x 5x 19
689:13x 53
152:2x 2x 2x 19
643:643
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
19 = 19
Therefore, the value for common factors is 19.
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 = 57575788920/(1x19)
LCM = 57575788920/19
LCM = 3030304680
Thus, we can understand that the LCM of 855,689,152,643 is 3030304680.
