Given numbers are 838,780,176,984
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 838,780,176,984 is 589583280.
Find LCM of 838,780,176,984 with Prime Factorization
| 2 | 838, 780, 176, 984 |
| 2 | 419, 390, 88, 492 |
| 2 | 419, 195, 44, 246 |
| 3 | 419, 195, 22, 123 |
| 419, 65, 22, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 419 x 65 x 22 x 41 = 589583280
Therefore, the lowest common multiple of 838,780,176,984 is 589583280.
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 780 x 176 x 984 = 113199989760
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
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
176 : 1, 2, 4, 8, 11, 16, 22, 44, 88, 176
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 838,780,176,984, is 2.
Now, the common factors can be found like this.
838:2x 419
780:2x 2x 3x 5x 13
176:2x 2x 2x 2x 11
984:2x 2x 2x 3x 41
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 3 = 96
Therefore, the value for common factors is 96.
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 = 113199989760/(2x96)
LCM = 113199989760/192
LCM = 589583280
Thus, we can understand that the LCM of 838,780,176,984 is 589583280.
