Given numbers are 409,702,946,880
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 409,702,946,880 is 5432272560.
Find LCM of 409,702,946,880 with Prime Factorization
2 | 409, 702, 946, 880 |
11 | 409, 351, 473, 440 |
409, 351, 43, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 409 x 351 x 43 x 40 = 5432272560
Therefore, the lowest common multiple of 409,702,946,880 is 5432272560.
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.
409 x 702 x 946 x 880 = 239019992640
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.
409 : 1, 409
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
946 : 1, 2, 11, 22, 43, 86, 473, 946
880 : 1, 2, 4, 5, 8, 10, 11, 16, 20, 22, 40, 44, 55, 80, 88, 110, 176, 220, 440, 880
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 409,702,946,880, is 1.
Now, the common factors can be found like this.
409:409
702:2x 3x 3x 3x 13
946:2x 11x 43
880:2x 2x 2x 2x 5x 11
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 11 = 44
Therefore, the value for common factors is 44.
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 = 239019992640/(1x44)
LCM = 239019992640/44
LCM = 5432272560
Thus, we can understand that the LCM of 409,702,946,880 is 5432272560.
