Given numbers are 506,670,405,356
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 506,670,405,356 is 2443995180.
Find LCM of 506,670,405,356 with Prime Factorization
| 2 | 506, 670, 405, 356 |
| 5 | 253, 335, 405, 178 |
| 253, 67, 81, 178 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 253 x 67 x 81 x 178 = 2443995180
Therefore, the lowest common multiple of 506,670,405,356 is 2443995180.
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.
506 x 670 x 405 x 356 = 48879903600
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.
506 : 1, 2, 11, 22, 23, 46, 253, 506
670 : 1, 2, 5, 10, 67, 134, 335, 670
405 : 1, 3, 5, 9, 15, 27, 45, 81, 135, 405
356 : 1, 2, 4, 89, 178, 356
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 506,670,405,356, is 1.
Now, the common factors can be found like this.
506:2x 11x 23
670:2x 5x 67
405:3x 3x 3x 3x 5
356:2x 2x 89
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 5 = 20
Therefore, the value for common factors is 20.
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 = 48879903600/(1x20)
LCM = 48879903600/20
LCM = 2443995180
Thus, we can understand that the LCM of 506,670,405,356 is 2443995180.
