Given numbers are 838,700,932,685
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,700,932,685 is 9362429300.
Find LCM of 838,700,932,685 with Prime Factorization
| 2 | 838, 700, 932, 685 |
| 2 | 419, 350, 466, 685 |
| 5 | 419, 175, 233, 685 |
| 419, 35, 233, 137 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 419 x 35 x 233 x 137 = 9362429300
Therefore, the lowest common multiple of 838,700,932,685 is 9362429300.
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.
838 x 700 x 932 x 685 = 374497172000
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.
838 : 1, 2, 419, 838
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
932 : 1, 2, 4, 233, 466, 932
685 : 1, 5, 137, 685
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,700,932,685, is 1.
Now, the common factors can be found like this.
838:2x 419
700:2x 2x 5x 5x 7
932:2x 2x 233
685:5x 137
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 5 = 40
Therefore, the value for common factors is 40.
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 = 374497172000/(1x40)
LCM = 374497172000/40
LCM = 9362429300
Thus, we can understand that the LCM of 838,700,932,685 is 9362429300.
