Find LCM of 115,666,311,869,780 with Prime Factorization
2 | 115, 666, 311, 869, 780 |
3 | 115, 333, 311, 869, 390 |
5 | 115, 111, 311, 869, 130 |
23, 111, 311, 869, 26 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 23 x 111 x 311 x 869 x 26 = 538177557060
Therefore, the lowest common multiple of 115,666,311,869,780 is 538177557060.
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.
115 x 666 x 311 x 869 x 780 = 16145326711800
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.
115 : 1, 5, 23, 115
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
311 : 1, 311
869 : 1, 11, 79, 869
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 115,666,311,869,780, is 1.
Now, the common factors can be found like this.
115:5x 23
666:2x 3x 3x 37
311:311
869:11x 79
780:2x 2x 3x 5x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 5 = 30
Therefore, the value for common factors is 30.
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 = 16145326711800/(1x30)
LCM = 16145326711800/30
LCM = 538177557060
Thus, we can understand that the LCM of 115,666,311,869,780 is 538177557060.
