Given numbers are 785,754,823,494,406
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 785,754,823,494,406 is 64787687510.
Find LCM of 785,754,823,494,406 with Prime Factorization
| 2 | 785, 754, 823, 494, 406 |
| 13 | 785, 377, 823, 247, 203 |
| 29 | 785, 29, 823, 19, 203 |
| 785, 1, 823, 19, 7 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 29 x 785 x 1 x 823 x 19 x 7 = 64787687510
Therefore, the lowest common multiple of 785,754,823,494,406 is 64787687510.
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.
785 x 754 x 823 x 494 x 406 = 97699832765080
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.
785 : 1, 5, 157, 785
754 : 1, 2, 13, 26, 29, 58, 377, 754
823 : 1, 823
494 : 1, 2, 13, 19, 26, 38, 247, 494
406 : 1, 2, 7, 14, 29, 58, 203, 406
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 785,754,823,494,406, is 1.
Now, the common factors can be found like this.
785:5x 157
754:2x 13x 29
823:823
494:2x 13x 19
406:2x 7x 29
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 13x 29 = 1508
Therefore, the value for common factors is 1508.
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 = 97699832765080/(1x1508)
LCM = 97699832765080/1508
LCM = 64787687510
Thus, we can understand that the LCM of 785,754,823,494,406 is 64787687510.
