Given numbers are 844,934,478,650,390
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 844,934,478,650,390 is 91846337700.
Find LCM of 844,934,478,650,390 with Prime Factorization
| 2 | 844, 934, 478, 650, 390 |
| 5 | 422, 467, 239, 325, 195 |
| 13 | 422, 467, 239, 65, 39 |
| 422, 467, 239, 5, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 422 x 467 x 239 x 5 x 3 = 91846337700
Therefore, the lowest common multiple of 844,934,478,650,390 is 91846337700.
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.
844 x 934 x 478 x 650 x 390 = 95520191208000
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.
844 : 1, 2, 4, 211, 422, 844
934 : 1, 2, 467, 934
478 : 1, 2, 239, 478
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 844,934,478,650,390, is 2.
Now, the common factors can be found like this.
844:2x 2x 211
934:2x 467
478:2x 239
650:2x 5x 5x 13
390:2x 3x 5x 13
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 5x 13 = 520
Therefore, the value for common factors is 520.
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 = 95520191208000/(2x520)
LCM = 95520191208000/1040
LCM = 91846337700
Thus, we can understand that the LCM of 844,934,478,650,390 is 91846337700.
