Given numbers are 520,935,660,821
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 520,935,660,821 is 239502120.
Find LCM of 520,935,660,821 with Prime Factorization
| 2 | 520, 935, 660, 821 |
| 2 | 260, 935, 330, 821 |
| 5 | 130, 935, 165, 821 |
| 11 | 26, 187, 33, 821 |
| 26, 17, 3, 821 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 11 x 26 x 17 x 3 x 821 = 239502120
Therefore, the lowest common multiple of 520,935,660,821 is 239502120.
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 935 x 660 x 821 = 263452332000
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
935 : 1, 5, 11, 17, 55, 85, 187, 935
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
821 : 1, 821
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,935,660,821, is 1.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
935:5x 11x 17
660:2x 2x 3x 5x 11
821:821
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 5x 5x 11 = 1100
Therefore, the value for common factors is 1100.
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 = 263452332000/(1x1100)
LCM = 263452332000/1100
LCM = 239502120
Thus, we can understand that the LCM of 520,935,660,821 is 239502120.
