Find LCM of 308,525,605,774,440 with Prime Factorization
| 2 | 308, 525, 605, 774, 440 |
| 2 | 154, 525, 605, 387, 220 |
| 3 | 77, 525, 605, 387, 110 |
| 5 | 77, 175, 605, 129, 110 |
| 7 | 77, 35, 121, 129, 22 |
| 11 | 11, 5, 121, 129, 22 |
| 1, 5, 11, 129, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 11 x 1 x 5 x 11 x 129 x 2 = 65557800
Therefore, the lowest common multiple of 308,525,605,774,440 is 65557800.
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.
308 x 525 x 605 x 774 x 440 = 33316473960000
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.
308 : 1, 2, 4, 7, 11, 14, 22, 28, 44, 77, 154, 308
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
605 : 1, 5, 11, 55, 121, 605
774 : 1, 2, 3, 6, 9, 18, 43, 86, 129, 258, 387, 774
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 308,525,605,774,440, is 1.
Now, the common factors can be found like this.
308:2x 2x 7x 11
525:3x 5x 5x 7
605:5x 11x 11
774:2x 3x 3x 43
440:2x 2x 2x 5x 11
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 7x 11x 11 = 508200
Therefore, the value for common factors is 508200.
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 = 33316473960000/(1x508200)
LCM = 33316473960000/508200
LCM = 65557800
Thus, we can understand that the LCM of 308,525,605,774,440 is 65557800.
