Find LCM of 758,988,319,304,640 with Prime Factorization
| 2 | 758, 988, 319, 304, 640 |
| 2 | 379, 494, 319, 152, 320 |
| 2 | 379, 247, 319, 76, 160 |
| 2 | 379, 247, 319, 38, 80 |
| 19 | 379, 247, 319, 19, 40 |
| 379, 13, 319, 1, 40 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 19 x 379 x 13 x 319 x 1 x 40 = 19112030080
Therefore, the lowest common multiple of 758,988,319,304,640 is 19112030080.
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.
758 x 988 x 319 x 304 x 640 = 46480457154560
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.
758 : 1, 2, 379, 758
988 : 1, 2, 4, 13, 19, 26, 38, 52, 76, 247, 494, 988
319 : 1, 11, 29, 319
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 758,988,319,304,640, is 1.
Now, the common factors can be found like this.
758:2x 379
988:2x 2x 13x 19
319:11x 29
304:2x 2x 2x 2x 19
640:2x 2x 2x 2x 2x 2x 2x 5
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 2x 2x 19 = 2432
Therefore, the value for common factors is 2432.
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 = 46480457154560/(1x2432)
LCM = 46480457154560/2432
LCM = 19112030080
Thus, we can understand that the LCM of 758,988,319,304,640 is 19112030080.
