Given numbers are 438,988,436,934,608
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 438,988,436,934,608 is 88111871328.
Find LCM of 438,988,436,934,608 with Prime Factorization
| 2 | 438, 988, 436, 934, 608 |
| 2 | 219, 494, 218, 467, 304 |
| 19 | 219, 247, 109, 467, 152 |
| 219, 13, 109, 467, 8 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 219 x 13 x 109 x 467 x 8 = 88111871328
Therefore, the lowest common multiple of 438,988,436,934,608 is 88111871328.
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.
438 x 988 x 436 x 934 x 608 = 107144035534848
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.
438 : 1, 2, 3, 6, 73, 146, 219, 438
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
436 : 1, 2, 4, 109, 218, 436
934 : 1, 2, 467, 934
608 : 1, 2, 4, 8, 16, 19, 32, 38, 76, 152, 304, 608
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 438,988,436,934,608, is 2.
Now, the common factors can be found like this.
438:2x 3x 73
988:2x 2x 13x 19
436:2x 2x 109
934:2x 467
608:2x 2x 2x 2x 2x 19
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 2x 19 = 608
Therefore, the value for common factors is 608.
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 = 107144035534848/(2x608)
LCM = 107144035534848/1216
LCM = 88111871328
Thus, we can understand that the LCM of 438,988,436,934,608 is 88111871328.
