Given numbers are 398,844,690,559,320
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 398,844,690,559,320 is 518258470080.
Find LCM of 398,844,690,559,320 with Prime Factorization
| 2 | 398, 844, 690, 559, 320 |
| 2 | 199, 422, 345, 559, 160 |
| 5 | 199, 211, 345, 559, 80 |
| 199, 211, 69, 559, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 199 x 211 x 69 x 559 x 16 = 518258470080
Therefore, the lowest common multiple of 398,844,690,559,320 is 518258470080.
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.
398 x 844 x 690 x 559 x 320 = 41460677606400
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.
398 : 1, 2, 199, 398
844 : 1, 2, 4, 211, 422, 844
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
559 : 1, 13, 43, 559
320 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 320
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 398,844,690,559,320, is 1.
Now, the common factors can be found like this.
398:2x 199
844:2x 2x 211
690:2x 3x 5x 23
559:13x 43
320:2x 2x 2x 2x 2x 2x 5
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 2x 2x 5 = 80
Therefore, the value for common factors is 80.
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 = 41460677606400/(1x80)
LCM = 41460677606400/80
LCM = 518258470080
Thus, we can understand that the LCM of 398,844,690,559,320 is 518258470080.
