The LCM of 520,666,814,979 is 169523640.
Find LCM of 520,666,814,979 with Prime Factorization
| 2 | 520, 666, 814, 979 |
| 11 | 260, 333, 407, 979 |
| 37 | 260, 333, 37, 89 |
| 260, 9, 1, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 11 x 37 x 260 x 9 x 1 x 89 = 169523640
Therefore, the lowest common multiple of 520,666,814,979 is 169523640.
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.
520 x 666 x 814 x 979 = 275984485920
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.
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
666 : 1, 2, 3, 6, 9, 18, 37, 74, 111, 222, 333, 666
814 : 1, 2, 11, 22, 37, 74, 407, 814
979 : 1, 11, 89, 979
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,666,814,979, is 1.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
666:2x 3x 3x 37
814:2x 11x 37
979:11x 89
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 11x 37 = 1628
Therefore, the value for common factors is 1628.
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 = 275984485920/(1x1628)
LCM = 275984485920/1628
LCM = 169523640
Thus, we can understand that the LCM of 520,666,814,979 is 169523640.
