Given numbers are 789,534,240,831,493
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,534,240,831,493 is 767155998480.
Find LCM of 789,534,240,831,493 with Prime Factorization
| 2 | 789, 534, 240, 831, 493 |
| 3 | 789, 267, 120, 831, 493 |
| 263, 89, 40, 277, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 263 x 89 x 40 x 277 x 493 = 767155998480
Therefore, the lowest common multiple of 789,534,240,831,493 is 767155998480.
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.
789 x 534 x 240 x 831 x 493 = 41426423917920
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.
789 : 1, 3, 263, 789
534 : 1, 2, 3, 6, 89, 178, 267, 534
240 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 40, 48, 60, 80, 120, 240
831 : 1, 3, 277, 831
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,534,240,831,493, is 1.
Now, the common factors can be found like this.
789:3x 263
534:2x 3x 89
240:2x 2x 2x 2x 3x 5
831:3x 277
493:17x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3 = 54
Therefore, the value for common factors is 54.
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 = 41426423917920/(1x54)
LCM = 41426423917920/54
LCM = 767155998480
Thus, we can understand that the LCM of 789,534,240,831,493 is 767155998480.
