Given numbers are 505,667,851,138
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 505,667,851,138 is 74777370.
Find LCM of 505,667,851,138 with Prime Factorization
| 23 | 505, 667, 851, 138 |
| 505, 29, 37, 6 |
Multiply the prime numbers at the bottom and the left side.
23 x 505 x 29 x 37 x 6 = 74777370
Therefore, the lowest common multiple of 505,667,851,138 is 74777370.
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.
505 x 667 x 851 x 138 = 39557228730
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.
505 : 1, 5, 101, 505
667 : 1, 23, 29, 667
851 : 1, 23, 37, 851
138 : 1, 2, 3, 6, 23, 46, 69, 138
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 505,667,851,138, is 1.
Now, the common factors can be found like this.
505:5x 101
667:23x 29
851:23x 37
138:2x 3x 23
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
23x 23 = 529
Therefore, the value for common factors is 529.
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 = 39557228730/(1x529)
LCM = 39557228730/529
LCM = 74777370
Thus, we can understand that the LCM of 505,667,851,138 is 74777370.
