The LCM of 220,915,922,935,780 is 4101729060.
Find LCM of 220,915,922,935,780 with Prime Factorization
| 2 | 220, 915, 922, 935, 780 |
| 2 | 110, 915, 461, 935, 390 |
| 3 | 55, 915, 461, 935, 195 |
| 5 | 55, 305, 461, 935, 65 |
| 11 | 11, 61, 461, 187, 13 |
| 1, 61, 461, 17, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 11 x 1 x 61 x 461 x 17 x 13 = 4101729060
Therefore, the lowest common multiple of 220,915,922,935,780 is 4101729060.
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.
220 x 915 x 922 x 935 x 780 = 135357058980000
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.
220 : 1, 2, 4, 5, 10, 11, 20, 22, 44, 55, 110, 220
915 : 1, 3, 5, 15, 61, 183, 305, 915
922 : 1, 2, 461, 922
935 : 1, 5, 11, 17, 55, 85, 187, 935
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 220,915,922,935,780, is 1.
Now, the common factors can be found like this.
220:2x 2x 5x 11
915:3x 5x 61
922:2x 461
935:5x 11x 17
780:2x 2x 3x 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 3x 5x 5x 5x 11 = 33000
Therefore, the value for common factors is 33000.
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 = 135357058980000/(1x33000)
LCM = 135357058980000/33000
LCM = 4101729060
Thus, we can understand that the LCM of 220,915,922,935,780 is 4101729060.
