Given numbers are 717,786,579,632,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 717,786,579,632,690 is 1317536571480.
Find LCM of 717,786,579,632,690 with Prime Factorization
| 2 | 717, 786, 579, 632, 690 |
| 3 | 717, 393, 579, 316, 345 |
| 239, 131, 193, 316, 115 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 239 x 131 x 193 x 316 x 115 = 1317536571480
Therefore, the lowest common multiple of 717,786,579,632,690 is 1317536571480.
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.
717 x 786 x 579 x 632 x 690 = 142293949719840
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.
717 : 1, 3, 239, 717
786 : 1, 2, 3, 6, 131, 262, 393, 786
579 : 1, 3, 193, 579
632 : 1, 2, 4, 8, 79, 158, 316, 632
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 717,786,579,632,690, is 1.
Now, the common factors can be found like this.
717:3x 239
786:2x 3x 131
579:3x 193
632:2x 2x 2x 79
690:2x 3x 5x 23
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 3x 3 = 108
Therefore, the value for common factors is 108.
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 = 142293949719840/(1x108)
LCM = 142293949719840/108
LCM = 1317536571480
Thus, we can understand that the LCM of 717,786,579,632,690 is 1317536571480.
