Given numbers are 491,363,901,845,840
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 491,363,901,845,840 is 7599020989560.
Find LCM of 491,363,901,845,840 with Prime Factorization
| 3 | 491, 363, 901, 845, 840 |
| 5 | 491, 121, 901, 845, 280 |
| 491, 121, 901, 169, 56 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 491 x 121 x 901 x 169 x 56 = 7599020989560
Therefore, the lowest common multiple of 491,363,901,845,840 is 7599020989560.
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.
491 x 363 x 901 x 845 x 840 = 113985314843400
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.
491 : 1, 491
363 : 1, 3, 11, 33, 121, 363
901 : 1, 17, 53, 901
845 : 1, 5, 13, 65, 169, 845
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 491,363,901,845,840, is 1.
Now, the common factors can be found like this.
491:491
363:3x 11x 11
901:17x 53
845:5x 13x 13
840:2x 2x 2x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5 = 15
Therefore, the value for common factors is 15.
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 = 113985314843400/(1x15)
LCM = 113985314843400/15
LCM = 7599020989560
Thus, we can understand that the LCM of 491,363,901,845,840 is 7599020989560.
