Find LCM of 912,690,758,790,808 with Prime Factorization
| 2 | 912, 690, 758, 790, 808 |
| 2 | 456, 345, 379, 395, 404 |
| 2 | 228, 345, 379, 395, 202 |
| 3 | 114, 345, 379, 395, 101 |
| 5 | 38, 115, 379, 395, 101 |
| 38, 23, 379, 79, 101 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 38 x 23 x 379 x 79 x 101 = 317161420080
Therefore, the lowest common multiple of 912,690,758,790,808 is 317161420080.
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.
912 x 690 x 758 x 790 x 808 = 304474963276800
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.
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
758 : 1, 2, 379, 758
790 : 1, 2, 5, 10, 79, 158, 395, 790
808 : 1, 2, 4, 8, 101, 202, 404, 808
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 912,690,758,790,808, is 2.
Now, the common factors can be found like this.
912:2x 2x 2x 2x 3x 19
690:2x 3x 5x 23
758:2x 379
790:2x 5x 79
808:2x 2x 2x 101
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 2x 2x 2x 3x 5 = 480
Therefore, the value for common factors is 480.
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 = 304474963276800/(2x480)
LCM = 304474963276800/960
LCM = 317161420080
Thus, we can understand that the LCM of 912,690,758,790,808 is 317161420080.
