Given numbers are 790,702,824,494
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 790,702,824,494 is 2170626120.
Find LCM of 790,702,824,494 with Prime Factorization
| 2 | 790, 702, 824, 494 |
| 13 | 395, 351, 412, 247 |
| 395, 27, 412, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 13 x 395 x 27 x 412 x 19 = 2170626120
Therefore, the lowest common multiple of 790,702,824,494 is 2170626120.
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.
790 x 702 x 824 x 494 = 225745116480
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.
790 : 1, 2, 5, 10, 79, 158, 395, 790
702 : 1, 2, 3, 6, 9, 13, 18, 26, 27, 39, 54, 78, 117, 234, 351, 702
824 : 1, 2, 4, 8, 103, 206, 412, 824
494 : 1, 2, 13, 19, 26, 38, 247, 494
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 790,702,824,494, is 2.
Now, the common factors can be found like this.
790:2x 5x 79
702:2x 3x 3x 3x 13
824:2x 2x 2x 103
494:2x 13x 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 13 = 52
Therefore, the value for common factors is 52.
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 = 225745116480/(2x52)
LCM = 225745116480/104
LCM = 2170626120
Thus, we can understand that the LCM of 790,702,824,494 is 2170626120.
