Given numbers are 372,855,685,723,947
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 372,855,685,723,947 is 3314937835980.
Find LCM of 372,855,685,723,947 with Prime Factorization
| 3 | 372, 855, 685, 723, 947 |
| 5 | 124, 285, 685, 241, 947 |
| 124, 57, 137, 241, 947 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 124 x 57 x 137 x 241 x 947 = 3314937835980
Therefore, the lowest common multiple of 372,855,685,723,947 is 3314937835980.
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.
372 x 855 x 685 x 723 x 947 = 149172202619100
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.
372 : 1, 2, 3, 4, 6, 12, 31, 62, 93, 124, 186, 372
855 : 1, 3, 5, 9, 15, 19, 45, 57, 95, 171, 285, 855
685 : 1, 5, 137, 685
723 : 1, 3, 241, 723
947 : 1, 947
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 372,855,685,723,947, is 1.
Now, the common factors can be found like this.
372:2x 2x 3x 31
855:3x 3x 5x 19
685:5x 137
723:3x 241
947:947
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 5 = 45
Therefore, the value for common factors is 45.
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 = 149172202619100/(1x45)
LCM = 149172202619100/45
LCM = 3314937835980
Thus, we can understand that the LCM of 372,855,685,723,947 is 3314937835980.
