Given numbers are 671,803,985,385
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,803,985,385 is 337737785.
Find LCM of 671,803,985,385 with Prime Factorization
| 5 | 671, 803, 985, 385 |
| 11 | 671, 803, 197, 77 |
| 61, 73, 197, 7 |
Multiply the prime numbers at the bottom and the left side.
5 x 11 x 61 x 73 x 197 x 7 = 337737785
Therefore, the lowest common multiple of 671,803,985,385 is 337737785.
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.
671 x 803 x 985 x 385 = 204331359925
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.
671 : 1, 11, 61, 671
803 : 1, 11, 73, 803
985 : 1, 5, 197, 985
385 : 1, 5, 7, 11, 35, 55, 77, 385
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,803,985,385, is 1.
Now, the common factors can be found like this.
671:11x 61
803:11x 73
985:5x 197
385:5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
5x 11x 11 = 605
Therefore, the value for common factors is 605.
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 = 204331359925/(1x605)
LCM = 204331359925/605
LCM = 337737785
Thus, we can understand that the LCM of 671,803,985,385 is 337737785.
