Given numbers are 420,501,806,979,545
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 420,501,806,979,545 is 3016337944620.
Find LCM of 420,501,806,979,545 with Prime Factorization
| 2 | 420, 501, 806, 979, 545 |
| 3 | 210, 501, 403, 979, 545 |
| 5 | 70, 167, 403, 979, 545 |
| 14, 167, 403, 979, 109 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 14 x 167 x 403 x 979 x 109 = 3016337944620
Therefore, the lowest common multiple of 420,501,806,979,545 is 3016337944620.
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.
420 x 501 x 806 x 979 x 545 = 90490138338600
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.
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
501 : 1, 3, 167, 501
806 : 1, 2, 13, 26, 31, 62, 403, 806
979 : 1, 11, 89, 979
545 : 1, 5, 109, 545
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 420,501,806,979,545, is 1.
Now, the common factors can be found like this.
420:2x 2x 3x 5x 7
501:3x 167
806:2x 13x 31
979:11x 89
545:5x 109
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 90490138338600/(1x30)
LCM = 90490138338600/30
LCM = 3016337944620
Thus, we can understand that the LCM of 420,501,806,979,545 is 3016337944620.
