Find LCM of 769,660,388,649,897 with Prime Factorization
| 2 | 769, 660, 388, 649, 897 |
| 2 | 769, 330, 194, 649, 897 |
| 3 | 769, 165, 97, 649, 897 |
| 11 | 769, 55, 97, 649, 299 |
| 769, 5, 97, 59, 299 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 11 x 769 x 5 x 97 x 59 x 299 = 868490774580
Therefore, the lowest common multiple of 769,660,388,649,897 is 868490774580.
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 660 x 388 x 649 x 897 = 114640782244560
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
660 : 1, 2, 3, 4, 5, 6, 10, 11, 12, 15, 20, 22, 30, 33, 44, 55, 60, 66, 110, 132, 165, 220, 330, 660
388 : 1, 2, 4, 97, 194, 388
649 : 1, 11, 59, 649
897 : 1, 3, 13, 23, 39, 69, 299, 897
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 769,660,388,649,897, is 1.
Now, the common factors can be found like this.
769:769
660:2x 2x 3x 5x 11
388:2x 2x 97
649:11x 59
897:3x 13x 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 11 = 132
Therefore, the value for common factors is 132.
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 = 114640782244560/(1x132)
LCM = 114640782244560/132
LCM = 868490774580
Thus, we can understand that the LCM of 769,660,388,649,897 is 868490774580.
