Given numbers are 786,693,544,945
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 786,693,544,945 is 740789280.
Find LCM of 786,693,544,945 with Prime Factorization
| 2 | 786, 693, 544, 945 |
| 3 | 393, 693, 272, 945 |
| 3 | 131, 231, 272, 315 |
| 7 | 131, 77, 272, 105 |
| 131, 11, 272, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 7 x 131 x 11 x 272 x 15 = 740789280
Therefore, the lowest common multiple of 786,693,544,945 is 740789280.
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 693 x 544 x 945 = 280018347840
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
693 : 1, 3, 7, 9, 11, 21, 33, 63, 77, 99, 231, 693
544 : 1, 2, 4, 8, 16, 17, 32, 34, 68, 136, 272, 544
945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 786,693,544,945, is 1.
Now, the common factors can be found like this.
786:2x 3x 131
693:3x 3x 7x 11
544:2x 2x 2x 2x 2x 17
945:3x 3x 3x 5x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 7 = 378
Therefore, the value for common factors is 378.
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 = 280018347840/(1x378)
LCM = 280018347840/378
LCM = 740789280
Thus, we can understand that the LCM of 786,693,544,945 is 740789280.
