Given numbers are 619,664,946,486
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 619,664,946,486 is 47241768024.
Find LCM of 619,664,946,486 with Prime Factorization
| 2 | 619, 664, 946, 486 |
| 619, 332, 473, 243 |
Multiply the prime numbers at the bottom and the left side.
2 x 619 x 332 x 473 x 243 = 47241768024
Therefore, the lowest common multiple of 619,664,946,486 is 47241768024.
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.
619 x 664 x 946 x 486 = 188967072096
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.
619 : 1, 619
664 : 1, 2, 4, 8, 83, 166, 332, 664
946 : 1, 2, 11, 22, 43, 86, 473, 946
486 : 1, 2, 3, 6, 9, 18, 27, 54, 81, 162, 243, 486
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 619,664,946,486, is 1.
Now, the common factors can be found like this.
619:619
664:2x 2x 2x 83
946:2x 11x 43
486:2x 3x 3x 3x 3x 3
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2 = 4
Therefore, the value for common factors is 4.
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 = 188967072096/(1x4)
LCM = 188967072096/4
LCM = 47241768024
Thus, we can understand that the LCM of 619,664,946,486 is 47241768024.
