Find LCM of 331,520,805,720,260 with Prime Factorization
| 2 | 331, 520, 805, 720, 260 |
| 2 | 331, 260, 805, 360, 130 |
| 2 | 331, 65, 805, 180, 130 |
| 5 | 331, 65, 805, 90, 65 |
| 13 | 331, 13, 161, 18, 13 |
| 331, 1, 161, 18, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 5 x 13 x 331 x 1 x 161 x 18 x 1 = 498803760
Therefore, the lowest common multiple of 331,520,805,720,260 is 498803760.
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.
331 x 520 x 805 x 720 x 260 = 25937795520000
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.
331 : 1, 331
520 : 1, 2, 4, 5, 8, 10, 13, 20, 26, 40, 52, 65, 104, 130, 260, 520
805 : 1, 5, 7, 23, 35, 115, 161, 805
720 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 16, 18, 20, 24, 30, 36, 40, 45, 48, 60, 72, 80, 90, 120, 144, 180, 240, 360, 720
260 : 1, 2, 4, 5, 10, 13, 20, 26, 52, 65, 130, 260
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 331,520,805,720,260, is 1.
Now, the common factors can be found like this.
331:331
520:2x 2x 2x 5x 13
805:5x 7x 23
720:2x 2x 2x 2x 3x 3x 5
260:2x 2x 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 2x 2x 2x 2x 5x 5x 5x 13 = 52000
Therefore, the value for common factors is 52000.
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 = 25937795520000/(1x52000)
LCM = 25937795520000/52000
LCM = 498803760
Thus, we can understand that the LCM of 331,520,805,720,260 is 498803760.
