Given numbers are 786,282,836,456
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,282,836,456 is 30883512.
Find LCM of 786,282,836,456 with Prime Factorization
| 2 | 786, 282, 836, 456 |
| 2 | 393, 141, 418, 228 |
| 3 | 393, 141, 209, 114 |
| 19 | 131, 47, 209, 38 |
| 131, 47, 11, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 19 x 131 x 47 x 11 x 2 = 30883512
Therefore, the lowest common multiple of 786,282,836,456 is 30883512.
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.
786 x 282 x 836 x 456 = 84497288832
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.
786 : 1, 2, 3, 6, 131, 262, 393, 786
282 : 1, 2, 3, 6, 47, 94, 141, 282
836 : 1, 2, 4, 11, 19, 22, 38, 44, 76, 209, 418, 836
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,282,836,456, is 2.
Now, the common factors can be found like this.
786:2x 3x 131
282:2x 3x 47
836:2x 2x 11x 19
456:2x 2x 2x 3x 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 3x 3x 19 = 1368
Therefore, the value for common factors is 1368.
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 = 84497288832/(2x1368)
LCM = 84497288832/2736
LCM = 30883512
Thus, we can understand that the LCM of 786,282,836,456 is 30883512.
