Given numbers are 789,634,374,438
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 789,634,374,438 is 6828585126.
Find LCM of 789,634,374,438 with Prime Factorization
| 2 | 789, 634, 374, 438 |
| 3 | 789, 317, 187, 219 |
| 263, 317, 187, 73 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 263 x 317 x 187 x 73 = 6828585126
Therefore, the lowest common multiple of 789,634,374,438 is 6828585126.
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 634 x 374 x 438 = 81943021512
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
634 : 1, 2, 317, 634
374 : 1, 2, 11, 17, 22, 34, 187, 374
438 : 1, 2, 3, 6, 73, 146, 219, 438
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 789,634,374,438, is 1.
Now, the common factors can be found like this.
789:3x 263
634:2x 317
374:2x 11x 17
438:2x 3x 73
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 3 = 12
Therefore, the value for common factors is 12.
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 = 81943021512/(1x12)
LCM = 81943021512/12
LCM = 6828585126
Thus, we can understand that the LCM of 789,634,374,438 is 6828585126.
