Find LCM of 769,618,768,515,656 with Prime Factorization
| 2 | 769, 618, 768, 515, 656 |
| 2 | 769, 309, 384, 515, 328 |
| 2 | 769, 309, 192, 515, 164 |
| 2 | 769, 309, 96, 515, 82 |
| 3 | 769, 309, 48, 515, 41 |
| 103 | 769, 103, 16, 515, 41 |
| 769, 1, 16, 5, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 3 x 103 x 769 x 1 x 16 x 5 x 41 = 12470350080
Therefore, the lowest common multiple of 769,618,768,515,656 is 12470350080.
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.
769 x 618 x 768 x 515 x 656 = 123306821591040
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.
769 : 1, 769
618 : 1, 2, 3, 6, 103, 206, 309, 618
768 : 1, 2, 3, 4, 6, 8, 12, 16, 24, 32, 48, 64, 96, 128, 192, 256, 384, 768
515 : 1, 5, 103, 515
656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,618,768,515,656, is 1.
Now, the common factors can be found like this.
769:769
618:2x 3x 103
768:2x 2x 2x 2x 2x 2x 2x 2x 3
515:5x 103
656:2x 2x 2x 2x 41
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 103 = 9888
Therefore, the value for common factors is 9888.
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 = 123306821591040/(1x9888)
LCM = 123306821591040/9888
LCM = 12470350080
Thus, we can understand that the LCM of 769,618,768,515,656 is 12470350080.
