Find LCM of 520,288,800,681 with Prime Factorization
| 2 | 520, 288, 800, 681 |
| 2 | 260, 144, 400, 681 |
| 2 | 130, 72, 200, 681 |
| 2 | 65, 36, 100, 681 |
| 2 | 65, 18, 50, 681 |
| 3 | 65, 9, 25, 681 |
| 5 | 65, 3, 25, 227 |
| 13, 3, 5, 227 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 2 x 2 x 3 x 5 x 13 x 3 x 5 x 227 = 21247200
Therefore, the lowest common multiple of 520,288,800,681 is 21247200.
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 288 x 800 x 681 = 81589248000
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
288 : 1, 2, 3, 4, 6, 8, 9, 12, 16, 18, 24, 32, 36, 48, 72, 96, 144, 288
800 : 1, 2, 4, 5, 8, 10, 16, 20, 25, 32, 40, 50, 80, 100, 160, 200, 400, 800
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,288,800,681, is 1.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
288:2x 2x 2x 2x 2x 3x 3
800:2x 2x 2x 2x 2x 5x 5
681:3x 227
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 2x 2x 2x 3x 5 = 3840
Therefore, the value for common factors is 3840.
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 = 81589248000/(1x3840)
LCM = 81589248000/3840
LCM = 21247200
Thus, we can understand that the LCM of 520,288,800,681 is 21247200.
