Given numbers are 140,323,921,754,702
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 140,323,921,754,702 is 141310374660.
Find LCM of 140,323,921,754,702 with Prime Factorization
| 2 | 140, 323, 921, 754, 702 |
| 3 | 70, 323, 921, 377, 351 |
| 13 | 70, 323, 307, 377, 117 |
| 70, 323, 307, 29, 9 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 13 x 70 x 323 x 307 x 29 x 9 = 141310374660
Therefore, the lowest common multiple of 140,323,921,754,702 is 141310374660.
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.
140 x 323 x 921 x 754 x 702 = 22044418446960
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.
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
323 : 1, 17, 19, 323
921 : 1, 3, 307, 921
754 : 1, 2, 13, 26, 29, 58, 377, 754
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 140,323,921,754,702, is 1.
Now, the common factors can be found like this.
140:2x 2x 5x 7
323:17x 19
921:3x 307
754:2x 13x 29
702:2x 3x 3x 3x 13
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 3x 13 = 156
Therefore, the value for common factors is 156.
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 = 22044418446960/(1x156)
LCM = 22044418446960/156
LCM = 141310374660
Thus, we can understand that the LCM of 140,323,921,754,702 is 141310374660.
