Given numbers are 840,136,932,677,538
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 840,136,932,677,538 is 605933658120.
Find LCM of 840,136,932,677,538 with Prime Factorization
| 2 | 840, 136, 932, 677, 538 |
| 2 | 420, 68, 466, 677, 269 |
| 2 | 210, 34, 233, 677, 269 |
| 105, 17, 233, 677, 269 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 105 x 17 x 233 x 677 x 269 = 605933658120
Therefore, the lowest common multiple of 840,136,932,677,538 is 605933658120.
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.
840 x 136 x 932 x 677 x 538 = 38779754119680
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.
840 : 1, 2, 3, 4, 5, 6, 7, 8, 10, 12, 14, 15, 20, 21, 24, 28, 30, 35, 40, 42, 56, 60, 70, 84, 105, 120, 140, 168, 210, 280, 420, 840
136 : 1, 2, 4, 8, 17, 34, 68, 136
932 : 1, 2, 4, 233, 466, 932
677 : 1, 677
538 : 1, 2, 269, 538
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 840,136,932,677,538, is 1.
Now, the common factors can be found like this.
840:2x 2x 2x 3x 5x 7
136:2x 2x 2x 17
932:2x 2x 233
677:677
538:2x 269
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 2 = 64
Therefore, the value for common factors is 64.
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 = 38779754119680/(1x64)
LCM = 38779754119680/64
LCM = 605933658120
Thus, we can understand that the LCM of 840,136,932,677,538 is 605933658120.
