Find LCM of 520,303,660,561,360 with Prime Factorization
| 2 | 520, 303, 660, 561, 360 |
| 2 | 260, 303, 330, 561, 180 |
| 2 | 130, 303, 165, 561, 90 |
| 3 | 65, 303, 165, 561, 45 |
| 5 | 65, 101, 55, 187, 15 |
| 11 | 13, 101, 11, 187, 3 |
| 13, 101, 1, 17, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 11 x 13 x 101 x 1 x 17 x 3 = 88391160
Therefore, the lowest common multiple of 520,303,660,561,360 is 88391160.
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 303 x 660 x 561 x 360 = 21001739616000
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
303 : 1, 3, 101, 303
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
561 : 1, 3, 11, 17, 33, 51, 187, 561
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 520,303,660,561,360, is 1.
Now, the common factors can be found like this.
520:2x 2x 2x 5x 13
303:3x 101
660:2x 2x 3x 5x 11
561:3x 11x 17
360:2x 2x 2x 3x 3x 5
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 3x 3x 3x 5x 5x 11 = 237600
Therefore, the value for common factors is 237600.
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 = 21001739616000/(1x237600)
LCM = 21001739616000/237600
LCM = 88391160
Thus, we can understand that the LCM of 520,303,660,561,360 is 88391160.
