Given numbers are 437,391,643,607
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 437,391,643,607 is 2899546129.
Find LCM of 437,391,643,607 with Prime Factorization
23 | 437, 391, 643, 607 |
19, 17, 643, 607 |
Multiply the prime numbers at the bottom and the left side.
23 x 19 x 17 x 643 x 607 = 2899546129
Therefore, the lowest common multiple of 437,391,643,607 is 2899546129.
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.
437 x 391 x 643 x 607 = 66689560967
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.
437 : 1, 19, 23, 437
391 : 1, 17, 23, 391
643 : 1, 643
607 : 1, 607
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 437,391,643,607, is 1.
Now, the common factors can be found like this.
437:19x 23
391:17x 23
643:643
607:607
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23 = 23
Therefore, the value for common factors is 23.
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 = 66689560967/(1x23)
LCM = 66689560967/23
LCM = 2899546129
Thus, we can understand that the LCM of 437,391,643,607 is 2899546129.
